PHP's PREG_PATTERN_ORDER is column-oriented, but 7 of the 10 call sites
read it row-wise, rebuilding each occurrence by indexing every column at
the same offset. Return an iterator of PregMatches instead, which is also
what the set-order and offset-capture variants were carrying, so the
three functions collapse into one and PregMatchesAll,
PregMatchesAllWithOffsets, CaptureKey and preg_match_map! all go away.
The offset-capture call sites are served by the new PregMatches
get_offset/name_offset accessors.
The search stays eager: regex::Captures borrows only the subject, so the
matches outlive the pattern resolved for the call, and PHP's
preg_match_all is eager too.

The two preg_match_all variants took the same arguments and differed
only in what they returned: a Vec of columns, or the named-and-numbered
PregMatchesAll. The latter is the one all but two call sites already
used, so preg_match_all2 takes over the plain PHP name and the Vec
variant goes away.
Its remaining readers only ever wanted group 0's column, which they now
take through CaptureKey::ByIndex(0); in the formatter this replaces the
array_shift that popped that column off the PREG_PATTERN_ORDER array.

preg_match copied every group into a Vec<Option<String>> while
preg_match2 handed back the borrowed captures. They now differ only in
the offset argument, so preg_match delegates with offset 0 and its
callers read groups through PregMatches::get.
Going through preg_match2 also makes preg_match honour the PCRE A
modifier, which it used to ignore; no caller passes such a pattern.
VersionParser::manipulate_version_string takes an index accessor instead
of a slice, and VersionParser::normalize matches against a copy of the
subject because the captures outlive the assignments to $version.

PregMatches was an IndexMap of owned Strings copied out of the match, so
every preg_match2/preg_replace_callback call allocated a String per
capture group (twice over for a named group) whether or not the caller
read it. It now wraps the regex::Captures itself, held alongside the
pattern it came from so groups stay reachable by both their named and
their numbered form, and hands out &str borrowed from the subject. The
subject's lifetime becomes a parameter of the type.

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.

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.

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.

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.
