Two compounding bugs that bit hermes (and any other workspace that
reaches main.py:142):
1. workspace/lib/ was in EXCLUDE_DIRS so the published wheel didn't
contain the directory at all. main.py imports `from lib.pre_stop
import read_snapshot` (and `build_snapshot`, `write_snapshot`) so
every workspace startup that reaches the snapshot path crashed
with `ModuleNotFoundError: No module named 'lib'`.
2. Even if lib/ had shipped, `lib` wasn't in SUBPACKAGES so the
import-rewriter would have left the bare `from lib.pre_stop`
unqualified — it would still fail because the package would only
be reachable as `molecule_runtime.lib`.
Fix: move `lib` from EXCLUDE_DIRS to SUBPACKAGES (one entry each).
Drift gate extension: the existing gate I added in #2163 only
asserted TOP_LEVEL_MODULES against workspace/*.py. This change adds
the symmetric assertion for SUBPACKAGES against workspace/<dir>/
(filtered by EXCLUDE_DIRS + presence of __init__.py). Catches both:
- Subpackage added to workspace/ but missed in SUBPACKAGES
- Subpackage missing from workspace/ but lingering in SUBPACKAGES
- Subpackage wrongly in EXCLUDE_DIRS while also referenced by
rewritten imports (the lib case)
Tested locally: build of 0.1.99 now ships lib/ and main.py contains
`from molecule_runtime.lib.pre_stop import ...` correctly rewritten.
