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.

diagnose used to read hardcoded shim stubs, so it described a fictional
runtime: OPENSSL_VERSION_NUMBER was always 0 and tripped the TLSv1.1/1.2
check, PHP_BINARY and OPENSSL_VERSION_TEXT were empty, and the extension,
function and ini probes answered from a fixed table.
The PHP worker gained a `diagnose` entry that returns every fact the
command needs as one PHP array, cached in a OnceLock so the several call
sites share a single round trip. Reading it back needed array support in
the serialize() parser, which in turn lets get_loaded_extensions and
get_all_ini_files return real lists instead of comma-joined strings.
Also fixes the openssl_version message, which dropped strstr()'s
before_needle argument during the port, and check_connectivity's
allow_url_fopen test, which did not follow PHP string truthiness.

The b'>' match arm in strip_tags's state machine never pushed the
character to the output buffer when encountered outside a tag (state
0), unlike every other special-character arm (!, ?, -, and the
catch-all) which does push in that state. Every literal '>' not part
of an HTML-like tag was silently dropped.
This corrupted "=>" into "=" in Composer's operation trace strings
(e.g. "Upgrading foo/bar (1.0.0 => 1.1.0)"), which go through
strip_tags to remove the <info>/<comment> markup before comparison,
un-ignoring 82 integration tests that were asserting on that exact
arrow.

shirabe_php_shim::chr() returned a Rust String, which lossily
re-encodes bytes >= 0x80 as UTF-8 replacement characters. ip_get_mask,
ip_get_network, and ip_map_to_6 relied on chr() to build raw in_addr
and netmask byte arrays, corrupting IPv4-in-IPv6 mappings and CIDR
netmasks. Build the Vec<u8> byte arrays directly instead of
round-tripping through String, and un-ignore test_ip_address and
test_ip_range now that the underlying bug is fixed.
chr()'s only other caller (http_downloader.rs, an ASCII ESC byte in a
regex pattern) didn't need the indirection either, so remove the shim
function entirely.

Port autoload_generator (24), bitbucket (14), suggested_packages (11),
git_driver (6), archive_manager (3), and a bump command test. Fix the
ApplicationTester output-capture root cause (php://memory streams must be
readable regardless of fopen mode). Implement posix_getuid/geteuid, the PCRE
'A' anchored modifier, php_strip_whitespace, stream_get_wrappers, is_callable
scalars; fix preg_quote angle-bracket escaping and class-map parser regexes.

Implement the bulk of string.rs shims:
- sprintf() with flags/width/precision/positional args for the common
conversions (s/d/u/b/o/x/X/c/f/F)
- pack()/unpack() for the C/c/n/v/N/V (+ s/S/i/I unpack) format codes
- base64_encode()/base64_decode() (non-strict)
- substr_replace, str_bitand, chr, hexdec, stripcslashes, addcslashes,
number_format (round-half-away-from-zero), uniqid, strip_tags,
html_entity_decode, iconv (UTF-8/ASCII identity)
%e/%E/%g/%G, wordwrap, sscanf, php_strip_whitespace and non-UTF-8 iconv
remain TODO(phase-d) (exact float-exponent/tokenizer/encoding-table
behavior not yet ported). Divergences in ported functions are noted with
TODO(phase-d) comments.

Implement array_unique, array_splice, array_merge_recursive, krsort,
ksort, asort, sort_with_flags and sort_natural_flag_case, plus the
strnatcmp/strnatcasecmp port they rely on. Drop array_key_last and
array_splice_mixed in favour of existing helpers at the call sites.
