What

Fixes #4202.

When --modules points at title-owned ELF modules, the audit now discovers each module's <executable>.<module>.guest.prx.registry.json sidecar beside the executable registry and includes those imports in the same report. A missing sidecar fails with a diagnostic that names the module and tells the user to rerun relinker with --registry. Explicitly supplied sidecars remain supported and are deduplicated. Updated the usage example to show the single-registry command.

Tested

Windows native, Python from D:\anyps5_work\tools\python:

• python -m unittest discover -s tools/tests -p "test_*.py" — 264 passed, 2 skipped.
• python tools/check_conventions.py --base origin/main --head HEAD — passed.
• git diff --check origin/main...HEAD — passed.

No title package was available; no title runtime was run.

Checklist

Closing this PR to avoid duplicating the broader --modules import audit already under review in #4559. That PR parses guest modules' dynamic imports, including sectionless PRX files, directly, so the registry-sidecar discovery added here is not needed to cover #4202. I missed #4559 during the initial open-PR search; sorry for adding parallel review work. The changes and Windows test results remain available on this branch if maintainers find the sidecar path useful later.
