docs(architecture): Consolidate into single /docs/architecture directory (31→20 files)

Unified Architecture Documentation:
- Eliminated redundant two-branch architecture directory
- Moved all architecture docs to single location: /docs/architecture
- Removed duplicates and outdated files

Changes Summary:
1. Moved 6 unique files from two-branch/docs/architecture/ to root:
   - AGENT_TOOL_LANGUAGE_MATRIX.md
   - BUILD_TOOL_DETECTION_FLOW.md
   - COMPILATION_STRATEGY.md
   - DEPLOYMENT-ARCHITECTURE.md
   - TOOL-EXECUTION-PIPELINE.md (replaces old tool-execution-flow.md)
   - V9_WORKING_COMPONENTS.md

2. Removed 3 duplicate files:
   - /V9-SYSTEM-OVERVIEW.md (root duplicate)
   - two-branch/architecture/V9-SYSTEM-OVERVIEW.md (outdated)
   - two-branch/architecture/UNIVERSAL_FRAMEWORK_ARCHITECTURE.md (duplicate)

3. Removed 8 outdated root architecture files (Jun-Jul 2025):
   - agent-architecture.md (Jun 9 - superseded)
   - report-data-flow.md (Jun 23)
   - scheduling-strategy.md (Jun 23)
   - PR_VS_REPO_ANALYSIS_SPLIT.md (Jul 17)
   - SIMPLIFIED_PR_ANALYSIS_FLOW.md (Jul 17)
   - comparison-agent-architecture.md (Jul 29)
   - comparison-agent-refactor-summary.md (Jul 30)
   - tool-execution-flow.md (Jul 28 - replaced by TOOL-EXECUTION-PIPELINE)

4. Deleted two-branch/docs/architecture/ directory entirely

Final State:
- Before: 31 architecture files (22 root + 9 two-branch)
- After: 20 architecture files (all in /docs/architecture)
- Reduction: 35% (11 files removed/consolidated)

Canonical V9-SYSTEM-OVERVIEW.md kept at:
  packages/agents/src/two-branch/docs/next/V9-SYSTEM-OVERVIEW.md

Benefits:
- Single source of truth for architecture documentation
- Eliminated confusion from duplicate files
- Removed outdated documentation
- Clearer organization

+
+**Analysis**:
+- Location 1 and 2 are identical (same MD5 hash)
+- Location 2 is the newest (Oct 31 12:58)
+- Location 3 is oldest and different content
+
+**Action**:
+- ✅ KEEP: `/packages/agents/src/two-branch/docs/next/V9-SYSTEM-OVERVIEW.md`
+- ❌ DELETE: `/V9-SYSTEM-OVERVIEW.md` (duplicate)
+- ❌ DELETE: `/packages/agents/src/two-branch/docs/architecture/V9-SYSTEM-OVERVIEW.md` (outdated)

+
+**Action**: Need to review both to determine which is canonical or if merge needed

+
+## 📁 Outdated/Historical Files in Root
+
+### Likely Outdated (Jun-Jul 2025):
+1. **agent-architecture.md** (Jun 9) - Superseded by updated-architecture-document-v4.md?
+2. **report-data-flow.md** (Jun 23) - V9 report flow likely updated
+3. **scheduling-strategy.md** (Jun 23) - Likely superseded
+4. **PR_VS_REPO_ANALYSIS_SPLIT.md** (Jul 17) - V9 may have resolved this
+5. **SIMPLIFIED_PR_ANALYSIS_FLOW.md** (Jul 17) - Check if still relevant
+6. **comparison-agent-architecture.md** (Jul 29) - Check against V9
+7. **comparison-agent-refactor-summary.md** (Jul 30) - Refactor completed?
+8. **tool-execution-flow.md** (Jul 28) - Superseded by two-branch TOOL-EXECUTION-PIPELINE?
+
+### Potentially Consolidated:
+1. **model-selection-architecture.md** (Aug 13)
+2. **dynamic-model-selection-architecture.md** (Aug 13) - Merge these two?
+3. **model-version-management.md** (Aug 13)
+
+---
+
+## 🎯 Recommended Actions
+
+### Phase 1: Remove Duplicates (2 files)
+```bash
+# Delete root V9-SYSTEM-OVERVIEW duplicate
+rm /Users/alpinro/Code\ Prjects/codequal/V9-SYSTEM-OVERVIEW.md
+
+# Delete outdated two-branch architecture V9-SYSTEM-OVERVIEW
+rm /Users/alpinro/Code\ Prjects/codequal/packages/agents/src/two-branch/docs/architecture/V9-SYSTEM-OVERVIEW.md
+```
+
+### Phase 2: Archive Outdated Root Architecture (8 files)
+Archive to `/docs/architecture/archive/2025-q2-q3/`:
+```
+1. agent-architecture.md (Jun 9)
+2. report-data-flow.md (Jun 23)
+3. scheduling-strategy.md (Jun 23)
+4. PR_VS_REPO_ANALYSIS_SPLIT.md (Jul 17)
+5. SIMPLIFIED_PR_ANALYSIS_FLOW.md (Jul 17)
+6. comparison-agent-architecture.md (Jul 29)
+7. comparison-agent-refactor-summary.md (Jul 30)
+8. tool-execution-flow.md (Jul 28)
+```
+
+### Phase 3: Consolidate Model Selection Docs (3→1)
+Merge into `MODEL_SELECTION_ARCHITECTURE.md`:
+- model-selection-architecture.md
+- dynamic-model-selection-architecture.md
+- model-version-management.md
+
+### Phase 4: Resolve UNIVERSAL_FRAMEWORK_ARCHITECTURE
+**Need manual review**: Determine which version is canonical or merge both
+
+---
+
+## 📊 Expected Impact
+
+**Before**: 31 total architecture files
+- Root: 22 files
+- Two-branch architecture: 9 files
+
+**After Cleanup**:
+- Root: 12 files (22 - 8 archived - 2 consolidated + 1 merged)
+- Two-branch architecture: 8 files (9 - 1 duplicate removed)
+- **Total**: 20 files (35% reduction)
+
+**Archived**: 8 historical files → `/docs/architecture/archive/2025-q2-q3/`
+**Deleted**: 2 duplicates
+**Merged**: 3 model selection docs → 1
+
+---
+
+## ⚠️ Manual Review Needed
+
+1. **UNIVERSAL_FRAMEWORK_ARCHITECTURE.md** - Which version is correct?
+2. **tool-execution-flow.md** vs **TOOL-EXECUTION-PIPELINE.md** - Are these same/different?
+3. **architecture-addendum-2025-08-08.md** - Still relevant or merged into v4?
+
+---
+
+## ✅ Next Steps
+
+1. Review this analysis
+2. Approve Phase 1 (remove duplicates)
+3. Approve Phase 2 (archive outdated)
+4. Manually review UNIVERSAL_FRAMEWORK_ARCHITECTURE versions
+5. Execute cleanup and commit
+
+**Status**: Ready for Review
