The capture groups were discarded at 162 of the preg_match call sites,
which only tested the Option. They now call preg_is_match, which lets the
regex engine skip capture tracking.

Every call site but one passed offset 0. The remaining one, the UTF-8
chunking loop in Application, slices the subject instead: its pattern has
no anchor or lookaround, so matching a suffix is equivalent to starting
the search at that offset.

Preg had shed everything it owned: after the last few rounds its methods
were one-line forwards to the shim's preg_*(), differing only in a
default argument or a wrapper the caller unwrapped anyway. The 460 call
sites now name the shim function, and shirabe-pcre is gone from the
workspace along with its LICENSE entry.
The forwards expand as they read: isMatch becomes
preg_match2(.., 0).is_some() (is_none() where PHP negates it), isMatch3
and match3 drop the .is_some(), matchAll counts through
preg_match_all2(..).occurrence_count(), and replace4/replace5 spell out
the limit and count arguments preg_replace2 takes. Callbacks are the one
place the shapes differ: preg_replace_callback carries an error out of
the callback, so the fourteen infallible closures wrap their result in
Ok() and expect() it back.
Config::process() is the fifteenth, and it drops the `error` cell it
captured to smuggle a failure past a closure that could only return a
String. The `?` in the closure now carries it, which is what the PHP
does -- a throw from the callback leaves preg_replace_callback at the
failing match rather than running the remaining replacements and
reporting the last error.
The module doc that explained why composer/pcre's exceptions and
*StrictGroups() variants have no counterpart moves to the shim's preg
module, where the functions it describes live.

PregMatches keyed both forms of a capture group through CaptureKey, so
every read built one: a usize wrapped in an enum, or worse, a String
allocated to name a group that regex::Captures can look up from a &str.
It now mirrors regex::Captures instead -- get() takes the group number,
name() the group name -- and the enum drops out of the type entirely.
That is 285 call sites across 59 files, and the named ones carry most of
the win: `matches.get(&CaptureKey::ByName("host".to_string()))` reads as
`matches.name("host")`. ProcessExecutor loses a `user_key` binding that
existed only to build the key once.
CaptureKey stays as the key type of PregMatchesAll and
PregMatchesAllWithOffsets, where numbered and named entries share one
IndexMap and a key type is the point. Five files still name it.
Also retargets the two preg_match_all comments that described the
occurrence count through `matches[&CaptureKey::ByIndex(0)].len()`, an
Index impl these types no longer carry.

is_match_named and is_match_with_indexed_captures reshaped a match into
a name-keyed map or a number-positioned vec, each allocating a String
per group up front for callers that then read one or two of them. Every
one of the eleven call sites ports a plain Preg::isMatch in PHP, so they
now call is_match3 and reach for the group they want through
get(&CaptureKey::ByIndex(N)) / get(&CaptureKey::ByName(..)), the same
way the rest of the tree already reads a match.
Falling out of that: PregNamedGroups existed only to type the first
variant; PregMatches::iter() only to build both; and PregMatches::pattern
only to give iter() the capture names. PregMatches is now a plain
wrapper over regex::Captures, so preg_replace_callback no longer clones
the resolved pattern for every match, and preg_match_map! is internal to
the shim again.
SvnDriver::get_file_content and get_change_date recover the flat
`isMatch(..) && $match[2] !== null` condition the PHP has, which the vec
shape had forced into a nested if.

Preg::match4 and Preg::replace_callback gave callers a
PregMatchedGroups: an IndexMap rebuilt from the match with an owned
String per group, plus a second String for a named group's name key.
That is the copy PregMatches shed when it started wrapping
regex::Captures, reinstated one layer up -- and nearly every regex call
in the tree goes through Preg rather than the shim's preg_* directly, so
almost nothing saw the borrow.
PregMatchedGroups existed only to drop the null (unmatched) groups the
old PregMatches held as Option<String> values. PregMatches::get reports
a non-participating group as None on its own, so the two read alike and
the type collapses into it. Call sites still reach groups through
get(&CaptureKey::ByIndex(N)); what changes is that the value arrives as
a &str borrowed from the subject, which the signatures now carry as a
lifetime.
Three places needed the borrow reckoned with rather than a mechanical
rewrite: PhpFileCleaner::clean and Problem::get_messages read their
groups out before mutating what the match borrows, and
Git::get_authentication_failure names the lifetime of its url argument,
which the result borrows instead of self.

`Composer\Pcre\Preg` fills `$matches` through a by-ref parameter, and the
port mirrored that with a `&mut` (or `Option<&mut>`) out-param plus a
bool or count return. Callers had to declare an empty map one line ahead
of the call, and the type never said the map is only meaningful when the
call matched. Return the matches instead:
- match3/match4/is_match3/is_match4 -> Option<PregMatchedGroups>
- is_match_named -> Option<PregNamedGroups>
- match_all2/is_match_all -> PregMatchesAll
- is_match_all_with_offsets3 -> PregMatchesAllWithOffsets
Nothing is lost: the bool is `Option::is_some()`, and the occurrence
count is the length of any one column of a PREG_PATTERN_ORDER map, now
spelled `PregMatchesAll::occurrence_count()`. is_match() still answers
the bool question directly for callers that want no groups.

The five IndexMap shapes that the preg_* functions and Preg fill in are
now distinct types generated by preg_match_map!, so a matches map no
longer interchanges with any other map of the same key and value type.
Index<usize> is kept alongside Index<&Q> because call sites such as
config_command and event_dispatcher reach for a group by its position in
the map rather than by its capture key.

The assoc flag was always a literal at every call site, so the boolean
carried no information the function name could not. json_decode_assoc
and json_decode_obj make the resulting PhpMixed shape visible at the
call site.

Porting mapped every PHP `protected` member onto `pub(crate)`, which is
wider than nearly all of them need. Each item demoted here is reached
only from the module that defines it, so the crate-wide visibility
conveyed nothing.
Every `pub(crate)` that survives has at least one reader in another
module of the same crate.

The binary called itself Composer everywhere: the application name, the
logo, --version, about, and every warning that talks about the running
program. Prompts to file a bug also pointed at Composer's issue tracker.
Add SHIRABE_VERSION and SHIRABE_RELEASE_DATE next to the Composer version
constants and report those, naming the Composer version this port tracks
alongside them. Composer::VERSION and getVersion() are untouched, so the
composer platform package, composer-runtime-api and the HTTP User-Agent
keep the value plugins and package repositories expect.
build.rs stamps the release date with the UTC date of the HEAD commit,
the way Composer's Compiler fills in @release_date@ when building the
phar. It now also fails the build when git cannot be read, instead of
letting COMPOSER_DEV_WARNING_TIME fall back to the tagged-release value
and suppress the outdated-build warning forever.
Messages about the Composer ecosystem keep their wording. Two of them are
pinned by upstream installer fixtures (Rule's "cannot be modified by
Composer" and SolverProblemsException's "you can run Composer with") and
stay as they are so those fixtures can keep being used verbatim.
The e2e list comparison against upstream Composer now skips the banner,
which cannot match by design, and compares everything below it as before.

str_contains(), str_starts_with() and str_ends_with() were thin wrappers
over the str methods of the same semantics. Call sites now use
contains()/starts_with()/ends_with() directly.

Move `Composer\Pcre` out of shirabe-external-packages and into its own
crate, so the path is `shirabe_pcre::preg::Preg` instead of
`shirabe_external_packages::composer::pcre::preg::Preg`.

Ported exceptions were flat structs reached with `downcast_ref`, so
Composer's `catch (\RuntimeException $e)` only matched the exact leaf
type and `get_class($e)` had nothing to report. Each exception now
embeds an instance of the class it extends and travels inside an
`AnyThrowable`; `Catch::catch`/`catch_mut` walk that chain, and
`PhpClass::php_class_name` yields the PHP FQCN.
Dropping the `std::error::Error` impls from the exception types leaves
`AnyThrowable` as the only route into an `anyhow::Error`, so the walk
cannot be bypassed. A `no_exception_downcast` linter catches the
`downcast::<X>()` calls that would now silently answer `None`.
Three sites change behavior as a result: the `TransportException`
exit-code override reaches `MaxFileSizeExceededException`, the
`catch (\LogicException)` in findSimilar() reaches its subclasses, and
rendered exception titles carry the real class name rather than a
guess. `get_class_err()` is no longer a `todo!()`, which re-enables
FilesystemRepositoryTest::testCorruptedRepositoryFile.

PHP's JsonFile::encode throws a RuntimeException when json_encode fails; the
port swallowed that into an .unwrap() marked TODO(phase-c). Return
anyhow::Result from encode/encode_with_options and propagate at every call
site (print_table and list_repositories become Result-returning to carry it).

regex::Regex::clone() does not share the underlying meta engine's
search-cache pool, so every fresh clone pays a ~10us warmup cost on
its first use. Two changes together eliminate this across nearly all
preg_* call sites:
- A php_regex! macro resolves PHP-style patterns to a per-call-site
&'static regex::Regex (via regex-macro's LazyLock), applied at the
majority of call sites throughout the codebase.
- Call sites still passing dynamic pattern strings go through
PATTERN_CACHE, which now stores Arc<(Regex, bool)> and hands out
Arc::clone()s instead of cloning the Regex itself.
PregPattern::resolve() returns a ResolvedPattern enum (Arc or
'static reference) rather than an owned Regex, so neither path ever
clones the Regex proper.

The `!@json_decode($children)` guards in addSubNode/removeSubNode were
translated as `is_null() || as_bool() == Some(false)`, which drops PHP's
other falsy cases (empty array/string, "0", 0). At the removeSubNode site
(assoc=true) this diverged from Composer: an empty object node decodes to
an empty array, which PHP treats as falsy and aborts on, but the Rust
guard kept going. Replace both with php_truthy, the faithful rendering of
PHP `!`, preserving the deliberate empty-`{}` behavior difference between
the assoc=false (addSubNode) and assoc=true (removeSubNode) sites.

ArrayObject was only a thin wrapper around IndexMap<String, PhpMixed>
used as an empty-{} vs empty-[] marker and as the assoc=false JSON
object representation; no reference semantics were involved. Inline its
payload directly into PhpMixed::Object and drop the type along with the
now-dead StdClass.
Side effects of the unification:
- ArrayObject::new was todo!(); the config --global / object-typed get
paths that built PhpMixed::Object(ArrayObject::new(None)) no longer
panic.
- base_config_command wrote 'config' as PhpMixed::Array(empty), emitting
[] instead of {}; now matches PHP's new \ArrayObject ({}).
- The dead is::<StdClass>()/is::<ArrayObject>() instanceof checks in
JsonManipulator are replaced with the faithful as_object() mapping.

unnecessarily. Store PhpMixed values directly and update all callers
accordingly.

so their anyhow::Result wrappers never carried an Err.

Rust's type system already distinguishes participating from
non-participating capture groups via Option, so the *StrictGroups
methods add no safety here. Remove them and switch callers to the
plain variants.

Change json_encode/json_encode_ex and JsonFile::encode/encode_with_options
to take a generic serde::Serialize value instead of &PhpMixed, implement
Serialize for PhpMixed/ArrayObject, and drop the PhpMixed::String wrapping
at JsonManipulator call sites in favor of passing raw values.

Replace the i64 bitmask + encode_with_indent split with a JsonEncodeOptions
struct (Default = JSON_UNESCAPED_SLASHES|JSON_PRETTY_PRINT|JSON_UNESCAPED_UNICODE,
default indent). encode/write each get a default form plus an explicit
encode_with_options/write_with_options variant, mirroring PHP's optional
$options argument. write_with_options always encodes with self.indent, matching
PHP write().
Also reconcile call sites with the PHP sources: most ported sites passed 0 where
Composer omits the argument (= default flags), so JsonManipulator/ShowCommand and
JsonConfigSource now use the default options; only ComposerRepository and Locker
genuinely pass 0.
