* feat(security): implement P0 security fixes for PR automation script (ADR-015)

Addresses 6 critical security issues identified by multi-agent review:

P0 Fixes Implemented:
1. Branch name validation - prevents command injection via Test-SafeBranchName
2. Worktree path validation - prevents path traversal via Get-SafeWorktreePath
3. Concurrency lock - prevents race conditions via Enter-ScriptLock/Exit-ScriptLock
4. Int64 CommentId - fixes overflow bug (GitHub IDs exceed Int32.MaxValue)
5. Workflow concurrency - already implemented (concurrency: group: pr-maintenance)
6. Rate limit pre-flight - prevents API exhaustion via Test-RateLimitSafe

Agent Review Summary:
- Architect: Created ADR-015 reconciling 5 agent reviews (roadmap, critic, security, devops, qa)
- High-Level-Advisor: Challenged timeline (1 week -> 2 weeks), promoted rate limit to P0
- Critic: APPROVED all 6 P0 fixes after implementation review

Files:
- scripts/Invoke-PRMaintenance.ps1: +170 lines (security validation region)
- .agents/architecture/ADR-015-pr-automation-reconciliation.md: Phase 1/2/3 prioritization
- .agents/sessions/2025-12-22-session-65-adr-015-reconciliation.md: Session log

* docs(analysis): comprehensive PR #249 review comment analysis

Analyzed 59 review comments (corrected from initial 47 estimate) across
4 reviewers with priority categorization and implementation strategy.

Priority Breakdown:
- P0 (Critical): 3 cursor[bot] HIGH severity bugs (BLOCKING)
  - Hardcoded main branch in conflict resolution
  - Scheduled runs bypass DryRun safety mode
  - Protected branch check blocks automation
- P1 (High): 4 critical bugs requiring immediate fix
- P2 (Medium): 47 comments (selective addressing)
- P3 (Low): 5 gemini code quality (defer to follow-up)

Key Insights:
- All 6 cursor[bot] comments verified as real bugs (100% actionability)
- ~15 of 42 rjmurillo comments are @copilot-directed (not for us)
- P0 issues violate ADR-015 requirements and break automation
- Estimated 2 hours for P0-P1 fixes

Analysis artifacts saved to .agents/pr-comments/PR-249/ (gitignored):
- analysis.md: Comprehensive analysis with grouped issues
- analyzed-comments.json: Structured data for automation

* fix: address P0-P1 cursor[bot] review comments on PR #249

P0 Critical Fixes (BLOCKING MERGE):
- Use PR target branch (baseRefName) instead of hardcoded 'main' in
  Resolve-PRConflicts to support non-main base branches
- Default dry_run to true for scheduled runs (ADR-015 safety requirement)
- Allow protected branch check to pass in CI environment (GITHUB_ACTIONS)

P1 High Priority Fixes:
- Add GH_TOKEN env var to workflow summary step for rate_limit API call
- Capture and log rate limit reset time for smarter scheduling
- Check $LASTEXITCODE after git push to detect failures
- Fix Test-RateLimitSafe tests to use correct multi-resource API format

Test improvements:
- Update rate limit tests to match actual function signature (no
  -MinimumRemaining param, uses $ResourceThresholds hashtable)
- Fix try/finally regex test to handle multiline content
