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.

Since Process is php-native with no Rust-fidelity obligation (see
plugin-class-classification.md), this port only needs to cover what
Rust-ported Composer code actually calls. Made the pipes/process_utils
modules pub(crate) (nothing outside symfony/process used them) and
rebuilt with `--force-warn dead_code` (normally allowed workspace-wide)
to find genuinely unreachable methods: Process lost 17 methods, 5
constants, and a private clone helper; ExecutableFinder lost two unused
suffix setters; AbstractPipes lost handle_error, whose only caller (a
stream_select error-handler registration) was never wired up.
Removing several of those setters (set_pty, set_idle_timeout,
disable_output/enable_output, set_options) then left the fields they
used to write with no remaining writer, so they hold one constant value
on every reachable path: pty always false, idle_timeout always None,
output_disabled always false, options always {suppress_errors,
bypass_shell}. Audited by value (not just call-graph reachability) and
removed everything that depended on the now-constant value:
- pty: is_pty(), is_pty_supported(), the PTY descriptor branch in
UnixPipes::get_descriptors(), and the now-unconstructed
Descriptor::Pty variant in shirabe-php-shim (plus its proc_open
match arm).
- idle_timeout: get_idle_timeout() and check_timeout()'s idle branch;
ProcessTimedOutException collapses to the single reachable timeout
type (dropped timeout_type/TYPE_GENERAL/TYPE_IDLE/is_general_timeout/
is_idle_timeout/get_exceeded_timeout).
- output_disabled: is_output_disabled(), build_callback()'s disabled
variant, get_descriptors()'s output_disabled term, and the
always-false guard in read_pipes_for_output()/ProcessFailedException
(its output section is now unconditional).
- options: Drop::drop()'s create_new_console branch can never fire
(that key can no longer exist), so it always just stops the process.
- has_callback/last_output_time: left write-only once their only
readers (the branches above) were gone.
- have_read_support: constant true once output_disabled collapsed, so
removed from PipesInterface, UnixPipes (incl. its /dev/null
null-stream branch), WindowsPipes, and Process::wait()'s dead guard.
No behavior change: every removed item/branch had zero callers, or was
constant on every reachable call site.

Extends no_banned_use to cover std::any::Any, std::io::Read/Write, and
std::process::Command, and teaches the linter to allow `as _` imports
so trait methods can still be brought into scope without binding the
banned name. Fully qualifies all existing usages across the codebase.

The stashed binary_installer port was blocked on posix_getpwuid (reached via
Platform::is_virtual_box_guest); implement it via getpwuid(3) extern "C". The
4 install-and-exec tests now pass with the stream I/O and Process cwd fixes.

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.

proc_open/proc_close/proc_get_status/proc_terminate represented the
process handle as a PhpMixed, which cannot hold a live child process or
its pipes, so they were stubs or todo!(). Model the handle as a new
PhpResource::Process variant and child pipes as a StreamBacking::Pipe,
with a native Descriptor enum for descriptorspec; proc_open now returns
io::Result and fills pipes as IndexMap<i64, PhpResource>.
Rewire the Symfony Process pipes and the Console terminal/cursor onto
the new types, removing the "PhpMixed cannot carry a PhpResource"
todo!()s. The remaining todo!()s are genuine syscall leaves
(proc_terminate signal delivery, stream_select, stream_set_blocking,
posix_kill, pty, fd>=3) left unimplemented since no syscall crate is
introduced.

Redesign PhpResource into a real stream handle (File/Memory backing with
tracked position, eof, closed state) and unify the whole fopen family
(fopen/fwrite/fread/fgets/fgetc/feof/fclose/ftell/fseek/rewind/fstat/
ftruncate/fflush and stream_get_contents/stream_copy_to_stream) on
&PhpResource, replacing the split PhpMixed/PhpResource APIs and their
todo!() stubs. fopen now returns Result; read functions stay String for
now (TODO(phase-e) to move to byte strings).
Propagate the signatures through callers: Process stdout/stderr, Cursor
input, curl header/body handles (extracted into typed maps keyed by job
id), Filesystem copy/safe_copy/files_are_equal, BufferIO, error_handler,
platform, perforce, zip. The proc_open pipe paths cannot carry a
PhpResource in a PhpMixed list, so they are left as todo!() with notes.

Run exec()/shell_exec()/system() through /bin/sh -c with PHP-faithful
line handling and return values. Port escapeshellcmd() (Unix branch,
including paired-quote handling) and escapeshellarg(). Implement
posix_isatty() via std::io::IsTerminal.
uid/signal/process-title helpers and proc_open-dependent status calls
remain TODO(phase-d): they need a libc/syscall crate or the deferred
process/signal subsystems.
