docs(plan): implementation plan for subagent-orchestration refactor
Three-round adversarial review incorporated. Covers:
- Architecture: main orchestrator + thin Haiku runner subagent
- File structure: SKILL.md + new references/runner.md
- Retry invariant: 2 codex invocations per round max; runner owns
full retry budget across all failure types; main treats every
failure as terminal for the current round
- Session-id lifecycle with two-tier positive content-bind
- Two-channel result protocol (JSON file + RUNNER_RESULT_AT line)
- user_warning channel for §2.4.4 no-op refresh diagnostic
- SKILL_DIR 3-tier resolution (user-scoped / plugin-marketplace / dev)
- Placeholder-substitution contract before prompt-body write
- Step 5 "VERY NEXT MESSAGE" wording reconciled with user_warning
- Task 7 E2E verification with skill-install, plan-mode test, and
residue-tax measurement
