feat: Implement phases 6 to 9 of the review cycle fix process, including discovery, batching, parallel planning, execution, and completion

- Added Phase 6: Fix Discovery & Batching with intelligent grouping and batching of findings.
- Added Phase 7: Fix Parallel Planning to launch planning agents for concurrent analysis and aggregation of partial plans.
- Added Phase 8: Fix Execution for stage-based execution of fixes with conservative test verification.
- Added Phase 9: Fix Completion to aggregate results, generate summary reports, and handle session completion.
- Introduced new frontend components: ResizeHandle for draggable resizing of sidebar panels and useResizablePanel hook for managing panel sizes with localStorage persistence.
- Added PowerShell script for checking TypeScript errors in source code, excluding test files.

+# Phase 5: Review Completion
+
+> Source: Shared from `commands/workflow/review-session-cycle.md` + `commands/workflow/review-module-cycle.md` Phase 5
+
+## Overview
+
+Finalize review state, generate completion statistics, and optionally prompt for automated fix pipeline.
+
+## Execution Steps
+
+### Step 5.1: Finalize State
+
+**Phase 5 Orchestrator Responsibilities**:
+- Finalize review-progress.json with completion statistics
+- Update review-state.json with completion_time and phase=complete
+- Progress tracking: Mark all tasks done
+
+**review-state.json updates**:
+```json
+{
+  "phase": "complete",
+  "completion_time": "2025-01-25T15:00:00Z",
+  "next_action": "none"
+}
+```
+
+**review-progress.json updates**:
+```json
+{
+  "phase": "complete",
+  "overall_percent": 100,
+  "completion_time": "2025-01-25T15:00:00Z",
+  "final_severity_distribution": {
+    "critical": 0,
+    "high": 3,
+    "medium": 12,
+    "low": 8
+  }
+}
+```
+
+### Step 5.2: Evaluate Completion Status
+
+**Full Success**:
+- All dimensions reviewed
+- Critical findings = 0
+- High findings <= 5
+- Action: Generate final report, mark phase=complete
+
+**Partial Success**:
+- All dimensions reviewed
+- Max iterations reached
+- Still have critical/high findings
+- Action: Generate report with warnings, recommend follow-up
+
+### Step 5.3: Progress Tracking Completion
+
+Update progress tracking to reflect all phases completed:
+```
+Phase 1: Discovery & Initialization     → completed
+Phase 2: Parallel Reviews (7 dimensions) → completed
+  → Security review                      → completed
+  → Architecture review                  → completed
+  → Quality review                       → completed
+  ... other dimensions as sub-items
+Phase 3: Aggregation                     → completed
+Phase 4: Deep-dive                       → completed
+Phase 5: Completion                      → completed
+```
+
+### Step 5.4: Fix Pipeline Prompt
+
+- Ask user: "Run automated fixes on findings? [Y/n]"
+- If confirmed AND --fix flag: Continue to Phase 6
+- Display summary of findings by severity:
+
+```
+Review Complete - Summary:
+  Critical: 0  High: 3  Medium: 12  Low: 8
+  Total findings: 23
+  Dimensions reviewed: 7/7
+  Iterations completed: 2/3
+
+Run automated fixes on findings? [Y/n]
+```
+
+## Completion Conditions
+
+**Full Success**:
+- All dimensions reviewed
+- Critical findings = 0
+- High findings <= 5
+- Action: Generate final report, mark phase=complete
+
+**Partial Success**:
+- All dimensions reviewed
+- Max iterations reached
+- Still have critical/high findings
+- Action: Generate report with warnings, recommend follow-up
+
+## Error Handling Reference
+
+### Phase-Level Error Matrix
+
+| Phase | Error | Blocking? | Action |
+|-------|-------|-----------|--------|
+| Phase 1 | Invalid path pattern / Session not found | Yes | Error and exit |
+| Phase 1 | No files matched / No completed tasks | Yes | Error and exit |
+| Phase 1 | Files not readable / No changed files | Yes | Error and exit |
+| Phase 2 | Single dimension fails | No | Log warning, continue other dimensions |
+| Phase 2 | All dimensions fail | Yes | Error and exit |
+| Phase 3 | Missing dimension JSON | No | Skip in aggregation, log warning |
+| Phase 4 | Deep-dive agent fails | No | Skip finding, continue others |
+| Phase 4 | Max iterations reached | No | Generate partial report |
+
+### CLI Fallback Chain
+
+Gemini -> Qwen -> Codex -> degraded mode
+
+### Fallback Triggers
+
+1. HTTP 429, 5xx errors, connection timeout
+2. Invalid JSON output (parse error, missing required fields)
+3. Low confidence score < 0.4
+4. Analysis too brief (< 100 words in report)
+
+### Fallback Behavior
+
+- On trigger: Retry with next tool in chain
+- After Codex fails: Enter degraded mode (skip analysis, log error)
+- Degraded mode: Continue workflow with available results
+
+## Best Practices
+
+1. **Start Specific**: Begin with focused module patterns for faster results
+2. **Expand Gradually**: Add more modules based on initial findings
+3. **Use Glob Wisely**: `src/auth/**` is more efficient than `src/**` with lots of irrelevant files
+4. **Trust Aggregation Logic**: Auto-selection based on proven heuristics
+5. **Monitor Logs**: Check reports/ directory for CLI analysis insights
+
+## Related Commands
+
+### View Review Progress
+
+Use `ccw view` to open the review dashboard in browser:
+
+```bash
+ccw view
+```
+
+### Automated Fix Workflow
+
+After completing a review, use the generated findings JSON for automated fixing:
+
+```bash
+# Step 1: Complete review (this skill)
+review-cycle src/auth/**
+# OR
+review-cycle
+
+# Step 2: Run automated fixes using dimension findings
+review-cycle --fix .workflow/active/WFS-{session-id}/.review/
+```
+
+## Output
+
+- State: review-state.json (phase=complete), review-progress.json (final)
+- Decision: fix pipeline or end
+
+## Next Phase
+
+- If fix requested: [Phase 6: Fix Discovery & Batching](06-fix-discovery-batching.md)
+- Else: Workflow complete
