fix(docs): address review feedback on architecture clarity and path consistency

- Clarify SPAWN exits vs HANDOFF continues in architecture diagram (S1)
- Add 'read' to toolsAllow in architecture snippet to match cron config (G2)
- Rephrase safety invariant 6 to clarify workers may push/manage labels (G3)
- Add reserved Rule 1 placeholder to explain numbering gap (S2)
- Clarify Rule 10 skip behavior for already-assigned PRs (S3)
- Standardize invariants checker path to full workspace path (G4/G5)
- Add note explaining SKILL.md deployment to workspace path (G1)
