Subject: feat(check-platform-reqs): implement command to verify PHP platform
 requirements

Collects platform requirements (php, ext-*, lib-*, composer-*-api) from
lock file, installed.json, and root composer.json, then compares them
against the detected PHP environment. Supports text/JSON output and
exit codes 0 (pass), 1 (failed), 2 (missing).

Extracts shared platform detection into a new platform.rs module,
reused by both check-platform-reqs and show --platform.
