Pin uv and uvx to the PM interpreter instead of ambient Python discovery.
A matching dependency stamp cannot prove that installed files still exist.
Repair now rebuilds the recorded workspace and lock in a fresh generation,
checks startup imports, and publishes the selection only after success.
Run startup recovery before dependency activation. Keep manual PM repair
reachable when the selected environment is damaged. Preserve plugin
selection, retry ownership, and the previous generation on failure.
Remove the separate pip, ensurepip, per-extra, and install-time quarantine
ladders. Keep orphan launcher restoration.
Verification: 717 targeted tests passed on native Windows ARM64, with
56 skipped. Ruff, diff checks, and the source-scoped compat check passed.
A disposable real Hermes install recovered deleted YAML and dotenv files,
then printed CLI help with exit 0. Its lock and stamp stayed unchanged.
The full suite and a release build were not run for this change.
