PHP fills `$matches` through a by-ref parameter, which the port mirrored
with a `&mut` out-param plus a bool or count return. Every caller then
had to declare an empty binding one line ahead of the call, and nothing
in the type said the binding is only meaningful when the call succeeded.
Return the matches instead: preg_match() and preg_match2() hand back an
Option, and the three preg_match_all* functions hand back the collection
they used to fill.
The occurrence count the two map-shaped preg_match_all* functions used
to return is the length of any one of the map's columns, so it is not
lost -- Preg::match_all() and friends derive it via occurrence_count().
preg_replace2() keeps its `count: Option<&mut usize>`: that one is not
derivable from the replaced string, and callers that do not want it pay
nothing for passing None.

preg_match_all() and preg_match_all_set_order() were the last preg_*
functions handing back a bare Vec<String>, where a group that did not
participate is indistinguishable from one that captured "". Hand back
Option<String> as the map-shaped functions already do; php_match_row(),
the last of the truncate-then-pad helpers, goes with them.
preg_split_delim_capture() keeps its Vec<String>. preg_split() accepts
no PREG_UNMATCHED_AS_NULL, so there is no null form to move it to, and
its result interleaves split segments -- which can never be absent --
with the captured delimiters.

The possessive quantifiers in Symfony's tag-matching patterns only
suppress backtracking: the open-tag class excludes backslash, so giving
a character back can never let the \\. alternative or the closing >
match, and the same holds for the close-tag class and >. Removing them
is the documented port for performance-only possessive quantifiers, not
an approximation waiting on a PCRE engine.

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.

preg_match2() and preg_match_all_offset_capture() each become a pair over
a shared private impl, and their flags arguments are gone: no caller passed
anything but 0 or PREG_UNMATCHED_AS_NULL. Preg::match5()/is_match5() lose
their own flags argument for the same reason -- both call sites passed 0,
and the value had nowhere left to go -- so they are renumbered to
match4()/is_match4(). PREG_UNMATCHED_AS_NULL itself is now unreferenced.

The two functions ran the same search and differed only in how they
reported a non-participating group: one as ("", 0) in a bespoke struct,
the other as (null, -1) in a capture-key map. Neither shape covered both
callers, because PHP reaches preg_match_all() with different flags from
each: Preg::matchAllWithOffsets() always ORs in PREG_UNMATCHED_AS_NULL,
while OutputFormatter::formatAndWrap() passes PREG_OFFSET_CAPTURE alone.
Keep the capture-key map, which also exposes named groups, and take the
flags that decide between null and "" for an unmatched group. The offset
is -1 either way, so the ("", 0) approximation is gone.

preg_replace_callback2 had one caller, Preg::replace_callback6, which
was itself reached only from Preg::replace_callback with the default
limit, count and flags. Fold the two shim functions into one and drop
those parameters along with replace_callback6.
The surviving callback takes callback2's IndexMap of matches: it can be
keyed by group name, and it omits trailing non-participating groups the
way PHP does, which is what the callbacks in Process and ProgressBar
test for.

SymfonyStyle modelled PHP's string|array message parameters, its array of
listing elements and its table headers/rows as PhpMixed, then normalised
and stringified them at every entry point. Take &[String] for the message
and listing parameters, Vec<Cell>/Vec<Row> for table (matching the
horizontal_table signature) and Vec<String> for the choice options, so the
is_array/is_iterable normalisation and the php_string helper both go away.
PhpMixed stays where PHP is genuinely mixed: the question answers returned
by ask/ask_hidden/choice, their validators, choice's string|int|null
default, and the progress_iterate elements.

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.

Split date() into date_utc() and date_local(), the latter resolving the
system's local timezone through the tzfile crate ($TZ, then
/etc/localtime, falling back to UTC when neither is readable). The
timestamps Composer renders for humans -- the GitHub OAuth token note,
the GitHub API rate limit reset time, the Perforce client spec fields and
the "today" check of the show command -- now go through date_local().
PHP resolves its default timezone from the date.timezone ini setting,
which Shirabe does not read, so date_default_timezone_get/set have no
input left to model and are dropped from the shim and its callers. The
resulting difference is recorded in docs/known-incompatibilities.md.

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.

The SignalHandler port was a no-op stub, so all four of Composer's abort
paths were dead code: nothing removed a half-created project, reverted
composer.json, or cleaned up half-installed packages.
Composer runs those handlers from pcntl callbacks, which a Rust signal
handler cannot do -- it may touch nothing beyond atomics. SignalSubscription
records the signal instead, and the abort runs from checkpoints on the normal
call stack, where the clean-up can borrow the state it needs. That also
resolves the closure-capture TODO(phase-c)s in RequireCommand and
InstallationManager, and replaces exit_with_last_signal's exit(0) with the
restore-and-re-raise Seld\Signal does.
A subscription is live only inside the four abort regions, so elsewhere the
signals keep their default disposition and kill the process at once. It is
installed without SA_RESTART so a signal interrupts an interactive prompt
rather than resuming the read. A signal reaches only the innermost
subscription, reproducing SignalHandler's single-stack dispatch.
Drop SignalRegistry, SignalableCommandInterface and the Application wiring
for them: nothing in Composer reaches that path, and SignalHandler discards
whatever they register. Signal handling from plugins and scripts is
undefined behavior; see docs/dev/signals.md.

Command::setProcessTitle has no caller: neither Composer nor the ported
Symfony Console code sets a process title, so run()'s title branch could
never fire. The shim it called into was unimplementable anyway — PHP
rewrites its own argv block, which Rust hands out only as owned copies.

Every parent module in the symfony-* crates already re-exported its leaf
modules with `pub use`, so each item was reachable by two paths. Make the
leaf modules private and route all callers through the single re-exported
path.

Table titles, per-column styles and appendRow have no callers: a
plugin-provided command runs inside the worker-side Symfony console
application, so its table rendering resolves against the real PHP
Table rather than this port. Remove those methods together with the
fields they were the only writers of, and the render branches those
fields made unreachable.

shirabe-symfony-console crate
Move `Symfony\Component\Console` out of shirabe-external-packages and
into its own crate, so the path is
`shirabe_symfony_console::application::Application` instead of
`shirabe_external_packages::symfony::console::application::Application`.
The `delegate_to_inner!` and `delegate_command_trait_impls_to_inner!`
macros move with it.
