Add error handling for runInit in container entrypoint

Addresses Sentry review feedback on PR #34. If runInit() throws
(e.g., git clone fails), the container would crash and restart
infinitely, preventing SSH access for debugging.

Now initialization failures are caught and logged as non-fatal,
allowing the SSH daemon to start so users can connect and debug.
