fix: guard os.userInfo() for UID-only containers, exclude HOME from cache key

Browse Source 
Address Greptile review feedback:

1. Wrap os.userInfo() in try/catch — it throws SystemError when the
   current UID has no /etc/passwd entry (e.g. `docker run --user 1234`
   with a minimal image). Falls back to process.env.HOME gracefully.

2. Add HOME to VOLATILE_ENV_KEY_EXACT so the discovery cache key is
   not affected by the caller-supplied HOME vs the resolved HOME.
   os.userInfo().homedir is constant for the process lifetime, so
   HOME adds no useful cache differentiation.
