Tighten Rm level validation

- Require the Rm level to stage or remove the tracked deleted file instead of treating the initial deleted worktree state as solved.
- Add a regression test proving read-only commands such as `ls` do not complete the Rm level.
- Verify the full JVM level solution suite with the compiled host Git runtime.
