The audit in .ken/php-shim-copying.md judged 14 functions in
shirabe-php-shim (plus php_wordwrap in shirabe-external-packages) to be
line-by-line transcriptions or structural imitations of php-src. PHP's
relicensing to 3-clause BSD makes keeping them legal, but the boundary
between BSD-derived and MIT code was invisible in the source tree.
Moving them into their own crate puts the license into the build
metadata (so NOTICE generation follows the binary), makes a reverse
dependency a compile error, and encodes the origin in the module path,
which mirrors php-src's ext tree. Each function records its origin in a
fixed-format doc comment, and a new php_src_derivation_boundary linter
fails if `php-src` appears in any Rust source outside the crate.
Public paths under shirabe_php_shim:: are unchanged: functions that are
themselves derived are re-exported with `pub use`, and the wrappers that
only validate arguments stay on the MIT side.
This also resolves the duplicate wordwrap implementation.
shirabe_php_shim::wordwrap was todo!(), so SymfonyStyle::block panicked,
while shirabe-external-packages carried its own copy. Both now go
through the single port, verified against real PHP on 13 cases covering
multi-character breaks and cut.

Two shim gaps made the extension-related branches of solver-problem
messages wrong:
- phpversion($ext) with a non-empty extension can't be known statically
(it's shirabe-php-shim's todo!()); Problem::get_missing_package_reason
now calls shirabe_php_rpc::phpversion, the same RPC bridge
platform::runtime::Runtime::get_extension_version already uses.
- extension_loaded's hardcoded allowlist was missing "pcre", a mandatory
always-compiled-in PHP extension, so ext-pcre was misreported as
"missing from your system" instead of "disabled by your platform
config" whenever a platform override disabled it.
Also fix XdebugHandler::getAllIniFiles() always returning `[""]`
(a php-runtime stub): create_extension_hint()'s early-return guard
(`paths[0] empty && len==1`) fired unconditionally, silently dropping
the entire "To enable extensions..." hint from every solver-problem
message that mentions missing extensions. shirabe-external-packages
can't depend on shirabe-php-rpc (shirabe-php-rpc already depends on
shirabe-external-packages), so IniHelper::get_all() queries a new
get_all_ini_files RPC command directly instead of going through the
stub.
This exposed that XdebugHandler is never constructed with a name
because bin/composer's restart-without-Xdebug bootstrap was never
ported to main.rs, making COMPOSER_ORIGINAL_INIS-driven behavior
unreachable; documented with a TODO(phase-c) and updated
ini_helper_test.rs's ignore reasons (and ignored test_with_no_ini,
which only passed before by coincidence with the old stub's constant
output) to match.

reload to PHP runtime
Rust has no PHP interpreter, so eval() can never be ported faithfully.
safely_load_installed_versions()'s job of priming Composer\InstalledVersions
before plugins run only matters within a single shared PHP process, which
the RPC-based plugin architecture does not have; the PHP runtime process
can call InstalledVersions::reload() itself instead.

Compiled Rust never loads a class by name, so the registered callback is dropped.
Return success so callers that register an autoloader during startup can proceed.
Kept the TODO(phase-d) comment: this is an unblocking stub, not a faithful
implementation.

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.

Port perforce (36), locker (10), composer_repository (7), installation_manager
(6), file_downloader (5), and event_dispatcher (6) tests via the mock infra.
Fix production porting bugs surfaced en route: BufferIO::get_output look-behind
regex, ComposerRepository list-form package iteration and initialize dispatch,
gethostname and spl_autoload_functions shims; add EventDispatcher get_listeners
test seam.

The PCRE delimiter `(?<!^|as|[=>< ,]) *(?<!-)[, ](?!-) *(?!,|as|$)` used to
split AND-constraints relies on look-around, which the regex crate cannot
compile (parse_constraints panicked). Reproduce its semantics in a hand-written
`split_and_constraints` scanner shared by VersionParser and RootPackageLoader.
Also model `method_exists` for the class-name form (shirabe runs no dumped
Composer ClassLoader) and un-ignore the InstalledVersions tests, serialized via
`#[serial]` since they share global static state.

Port php_version_compare (canonicalization + special-form ordering) and
expose it via version_compare()/version_compare_2(). Implement clone()
(via Clone), spl_object_hash()/spl_object_hash_process() (address-based),
get_loaded_extensions() and the main-version case of phpversion().
Interpreter/reflection/autoload/eval/$GLOBALS/memory-accounting and
Windows-only SAPI helpers remain TODO(phase-d): they have no equivalent
in the compiled shim.

json_encode/json_encode_ex now return anyhow::Result<String> instead of
Option, so callers no longer need json_last_error() to get the failure
reason.
