* feat: add implementation plan for PR review merge state verification

Session 85 lessons learned implementation plan:
- Add PR merge state verification to pr-review command (Skill-PR-Review-006)
- Create Test-PRMerged.ps1 script for GraphQL merge state checking
- Document Thread Resolution Protocol (Skills PR-Review-004, -005)
- Update Completion Criteria with merge verification

Prevents wasted effort on already-merged PRs where gh pr view returns stale data.

* feat: implement PR merge state verification (Issue #321)

Implements Session 85 lessons learned to prevent wasted effort on merged PRs.

Changes:
- Create Test-PRMerged.ps1 script to check PR merge state via GraphQL
  * Exit code 0 = not merged (safe to proceed)
  * Exit code 1 = merged (skip review work)
  * GraphQL API is source of truth (gh pr view may return stale data)

- Update pr-review command (.claude/commands/pr-review.md):
  * Add PR merge state verification to Step 1
  * Add Thread Resolution Protocol section (Skills PR-Review-004, -005)
  * Update Completion Criteria with PR merge check

- Thread Resolution Protocol documentation:
  * Single thread resolution (Skill-PR-Review-004)
  * Batch thread resolution using GraphQL mutation aliases (Skill-PR-Review-005)
  * Verification commands

Testing:
- ✅ Test-PRMerged.ps1 with merged PR #315 (exit code 1)
- ✅ Test-PRMerged.ps1 with open PR #320 (exit code 0)

Benefits:
- Prevents wasted effort when gh pr view returns stale state
- Reduces API calls via batch thread resolution (N calls → 1 call)
- Documents 2-step process: reply + resolve thread

Related: Session 85, PR #315, PR #320
Fixes #321

* docs: add Session 86 implementation log

Comprehensive documentation of PR review improvements implementation.

Deliverables:
- Issue #321 created
- Test-PRMerged.ps1 PowerShell script
- pr-review.md updates (merge verification + thread resolution protocol)
- Implementation plan document
- PR #322 created

Benefits:
- Prevents wasted effort on merged PRs
- Reduces API calls via batch thread resolution
- Documents critical 2-step process (reply + resolve thread)

Session metrics:
- 45 minutes implementation time
- 3 skills implemented (PR-Review-004, -005, -006)
- 2 tests executed (merged PR #315, open PR #320)
- 182 lines of code
