Fix gitignore and test suite per Codex review

- .gitignore: remove /bitlesson.md entry (plan AC-7 fix); keep /.claude/settings.json
  and .humanize/ entries which are valid bitlesson branch additions
- tests/run-all-tests.sh: remove 3 non-existent suites (test-continue-rlcr-loop.sh,
  test-ask-codex-routing.sh, test-codex-worker-routing.sh) that were silently skipped

All 1415 tests pass with no SKIP entries.
