docs: Add forge cleanup analysis and tools (#1128)

This commit adds documentation and tools for cleaning up duplicate PRs
and maintaining a clean forge, as requested in issue #1128.

Changes:
- Added docs/forge-cleanup-analysis.md - Detailed analysis of duplicate PRs
- Added docs/forge-cleanup-report.md - Comprehensive cleanup report
- Added scripts/cleanup-duplicate-prs.sh - Automated duplicate PR detection

The cleanup analysis identified and closed 4 duplicate PR groups:
- #1388 (duplicate of #1392)
- #1384 (duplicate of #1391)
- #1382 (duplicate of #1390)
- #1381 (duplicate of #1389)

Current PR status:
- 1 PR approved and ready to merge (#1386)
- 4 PRs awaiting review (#1392, #1391, #1390, #1389)
- 4 PRs requiring changes (#1387, #1380, #1379, #1374)

The cleanup script can be run to detect and close duplicate PRs:
  ./scripts/cleanup-duplicate-prs.sh --dry-run
  ./scripts/cleanup-duplicate-prs.sh --close

This addresses the cleanup work requested in issue #1128.

+- Closes older duplicates with explanatory comments
+- Supports dry-run mode for testing
+
+**Usage**:
+```bash
+# Dry run (default)
+./scripts/cleanup-duplicate-prs.sh
+
+# Actually close duplicates
+./scripts/cleanup-duplicate-prs.sh --close
+```
+
+### 2. Analysis Document
+**File**: `docs/forge-cleanup-analysis.md`
+
+**Contents**:
+- Detailed analysis of duplicate PRs
+- Review status of all open PRs
+- Policy recommendations
+- Implementation plan
+
+## Recommendations
+
+### 1. Immediate Actions
+1. **Merge approved PR #1386** (fleet audit tool)
+2. **Review PRs #1392, #1391, #1390, #1389** (awaiting review)
+3. **Address review comments** on PRs #1387, #1380, #1379, #1374
+
+### 2. Policy Implementation
+1. **Duplicate PR Prevention**:
+   - Implement check to detect if an open PR already exists for the same issue
+   - Add bot comment when duplicate PR is detected
+
+2. **PR Review Workflow**:
+   - Require at least one approval before merge
+   - Auto-close PRs with REQUEST_CHANGES after 7 days of inactivity
+
+3. **Stale PR Management**:
+   - Weekly cleanup of duplicate PRs
+   - Auto-close PRs older than 30 days with no activity
+
+### 3. Documentation Updates

+- **Duplicate PR Groups**: 4
+- **Stale PRs**: Unknown
+
+### After Cleanup:
+- **Open PRs**: 9
+- **Duplicate PR Groups**: 0
+- **Ready to Merge**: 1
+- **Awaiting Review**: 4
+- **Requiring Changes**: 4
+
+## Next Steps
+
+1. **Short-term** (this week):
+   - Merge PR #1386
+   - Review and merge PRs #1392, #1391, #1390, #1389
+   - Address review comments on remaining PRs
+
+2. **Medium-term** (next 2 weeks):

+
+3. **Long-term** (next month):
+   - Implement SOUL.md consolidation (issue #378)
+   - Deploy zero-change PR approval guard (issue #379)
+   - Establish regular forge cleanup cadence
+
+## Conclusion
+
+The forge cleanup has successfully reduced duplicate PRs and established tools and policies for ongoing maintenance. The immediate focus should be on merging the approved PR and reviewing the four PRs awaiting review.
+
+The cleanup tools and policies created will help prevent future accumulation of duplicate PRs and maintain a clean, efficient development workflow.
