chore: CLAUDE.md codex-review note, .gitignore additions, legacy buildcounter

Three small maintenance items accumulated during the M1/M2 session:

- .claude/CLAUDE.md: add "Codex will review your output once you are
  done!" note so the Codex review step is front-of-mind for agent work.
- .gitignore:
    * scripts/Deployment/build_and_upload_debug_agent_build_dev.ps1 —
      fill the gap next to the other two Legacy deployment scripts
      (already ignored).
    * plans/REFACTOR_AGENT_V2.md — the refactor plan stays local-only
      during active planning.
- src/Agent/AutopilotMonitor.Agent/buildcounter.txt: auto-incremented by
  MSBuild during the full-solution builds run for the M1/M2 gates.
