feat(php-shim): implement Phar/PharData and the zlib/bzip2 functions

Adopt the tar, flate2, and bzip2 crates to fill in the phar.rs and
compress.rs todos: PharData tar/zip reading, building, and whole-archive
compression, plus a native .phar reader that follows the php.net
file-format manual and verifies hash-based signatures. Callers now
propagate the constructor/extract errors PHP throws, and fwrite accepts
byte strings so gzread no longer needs lossy UTF-8.

The native .phar writing API stays todo!() (no call sites; Composer's
Compiler is not ported) and OPENSSL phar signatures are accepted
unverified (TODO(phase-c)).

This unblocks Tar::getComposerJson and the tar/phar/gzip downloaders;
tar_test (7), artifact_repository_test (2), and phar_archiver_test zip
(1) are un-ignored. The archive command itself still panics because
ArchiveManager::archive always generates glob excludes whose look-ahead
regexes the regex crate cannot compile; converting those patterns to
regex-compatible ones is a separate, still-undecided work item.
