chore: strip residual refs to deleted rules/commands from tooling-reference.md

[OriginalGary]

Summary

Final residual cleanup. tooling-reference.md described skills/rules that were deleted in the org-wide label-convention strip earlier today, leaving stale doctrine pointers and dead command descriptions.

Changes (.claude/rules/tooling-reference.md)

1. Drop the inline reference to pipeline-nevers.md in the intro paragraph.
2. Drop "serialize per parallelization.md" (file deleted).
3. Drop "(see parallelization.md §Orchestrator cwd preflight)" inline reference.
4. Drop the "sync-labels-style tooling bootstrap" phrasing in the gitignore implication note.
5. Delete the entire ## Operator commands section — it described /run, /merge, /unblock, /issue which were deleted in Open-Paws/structured-coding-with-ai#50.

🚦 How do rate limits work?
