feat(prime): add no-git-ops config to disable git ops in session close (GH#593)

Users who want manual control over git commits can now set:

  bd config set no-git-ops true

This makes `bd prime` output the stealth-mode session close protocol
(just `bd sync --flush-only`) instead of the full git add/commit/push
workflow. Useful when:

- You want to verify work before committing
- Claude tries to auto-commit after context compaction
- You have a custom git workflow

The --stealth flag still works as before for one-off use.
