`ProcessExecutor::execute_args` existed only to turn `execute`'s
`anyhow::Result` into an exit code of 1, so every one of its ~87 call
sites silently took the "command failed" branch on an error PHP would
have thrown. It is gone; callers use `execute` and propagate with `?`.
Where the enclosing function had no `Result` to propagate into, its
signature grew one, up to and including `Git::get_version`,
`Svn::binary_version`, `GitHub`/`GitLab`/`Bitbucket::authorize_oauth`,
`InitCommand::get_git_config` and `DiagnoseCommand::check_git`.
The VCS drivers had the same problem in the other direction: their
`get_contents` returned `Result<Response, Box<TransportException>>`, a
type too narrow for the PHP method, which lets any Throwable out of the
`catch (TransportException $e)` block. Every non-transport error was
therefore rewritten into a `TransportException` with code 0, which the
callers switch on. They now return
`anyhow::Result<Result<Response, Box<TransportException>>>`: the outer
`Result` carries what PHP does not catch, the inner one the exception
the drivers handle.
That signature also restores `GitLabDriver::getContents`: the 400/401
`TransportException`s it raises to force authentication are thrown
inside its own `try` block and handled by its own `catch`, but the port
returned them straight to the caller, so the authentication flow behind
them never ran.
`impl_php_exception!` gains `From<Box<$ty>> for anyhow::Error` so a
caught exception can be re-propagated with `?`.

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.

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.

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.

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.

The shim's filesystem entry points took `&str` even though each one resolves
to a local path through `std::fs` or a syscall, so callers holding a `PathBuf`
had to stringify it at the call site. They now take `impl AsRef<Path>`, the
form `file_exists`, `is_dir`, `unlink` and the rest of the already-converted
set use.
`Phar`, `PharData` and `ZipArchive` keep their archive path as a `PathBuf`.
`PharData::compress` names the compressed sibling by appending the suffix to
the file name rather than formatting the path into a `String`.
Arguments PHP resolves through a stream wrapper (`fopen`, `file_put_contents`,
`include`) still take `&str`, as do the byte-string operations (`dirname`,
`basename`, `pathinfo`) and archive-internal entry names, which are `/`-joined
logical names rather than OS paths.

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.

fallback paths
VcsDriverInterface::get_source/get_dist were made fallible in the Rust
port even though PHP's are infallible, forcing GitBitbucketDriver's
fallback delegation to silently swallow errors via
unwrap_or_default()/ok().flatten(). Make the trait infallible to match
PHP, updating the mechanical Ok(...) wrapping in all implementors.
Also narrow attempt_clone_fallback's cleanup to only trigger on
RuntimeException, mirroring PHP's catch (\RuntimeException $e), using
the same downcast pattern already used by has_composer_file for
TransportException.

Replace the libcurl-shim CurlDownloader with a reqwest+tokio implementation per
the .ken sketch, resolving the construction panic that blocked command tests
(mock path via __new_mock is untouched). Port remote_filesystem (7), hg/svn
driver (4), zip_archiver/git_exclude_filter (4) tests. Fix hg/svn/git_exclude
regex-delimiter and svn result-propagation porting bugs.

Take config and process as shared Rc<RefCell<..>> handles matching the
struct fields and Util\Git's constructor, assigning them directly. PHP
stores the same Config object reference, so sharing the Rc is faithful;
update the three call sites to pass cloned handles.

The Preg methods panic on PCRE failure (per the file header rationale),

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.

Resolve category F phase-b TODOs (class-string, instanceof, get_class,
method_exists, __FILE__, Reflection API, downcast).
- VcsRepository: dispatch drivers through a VcsDriverKind enum
(instantiate/supports/php_class_name) and add constructors to the
concrete VCS drivers
- repository downcasts via RepositoryInterfaceHandle::downcast_rc and
as_any (init/show commands, vcs ValidatingArrayLoader)
- BaseCommand::is_self_update_command override replaces an instanceof
- Factory::create narrows PartialComposer to ComposerHandle via as_full
- InstalledVersions gains set_self_dir/set_installed_is_local_dir,
replacing Reflection-based static property mutation
- ClassLoader::as_array_iter ports the PHP (array) cast
- drop the unnecessary __FILE__ phar branch in self-update
application get_class(command) reclassified TODO(plugin); buffer_io
StreamableInputInterface downcast and the ValidatingArrayLoader trait
redesign left as tracked TODOs.

Reconcile the VcsDriverInterface trait with the concrete drivers so every
driver implements it as in PHP, where each driver extends VcsDriver.
- Make cache-mutating getters take &mut self in the trait, matching the
inherent methods' lazy-cache semantics; update vcs_repository consumers.
- Change supports() to take Rc<RefCell<Config>> and return Result<bool>,
completing GitDriver::supports deep ls-remote and its config wiring.
- Add base get_composer_information to Git/Hg/Fossil/Perforce and an
impl VcsDriverInterface block to every driver, delegating to inherent
methods and absorbing type differences in the impl.

Implement BaseCommand trait and other abstract class traits across
all command, downloader, io, package, and VCS driver types. Also
fix trait method signatures for composer_mut and io_mut to return
mutable references to Option rather than Option of mutable references.
