feat: Implement workflow phases for test generation and execution

- Added Phase 1: Session Start to detect input mode and create test workflow session.
- Added Phase 2: Test Context Gather to gather test context via coverage analysis or codebase scan.
- Added Phase 3: Test Concept Enhanced to analyze test requirements using Gemini and generate multi-layered test requirements.
- Added Phase 4: Test Task Generate to create test-specific tasks based on analysis results.
- Added Phase 5: Test Cycle Execute to manage iterative test execution and fix cycles with adaptive strategies.
- Introduced BottomPanel component for terminal dashboard with Queue and Inspector tabs.

+# Phase 3: Test Coverage Analysis
+
+Analyze existing test coverage, detect test framework, and identify coverage gaps.
+
+## Objective
+
+- Analyze existing codebase for test patterns and conventions
+- Detect current test coverage and framework
+- Identify related components and integration points
+- Generate test-context-package.json
+
+## Execution
+
+### Step 3.1: Execute Test Context Gathering
+
+```javascript
+Skill(skill="workflow:tools:test-context-gather", args="--session [sessionId]")
+```
+
+**Purpose**: Analyze existing codebase for:
+- Existing test patterns and conventions
+- Current test coverage
+- Related components and integration points
+- Test framework detection
+
+### Step 3.2: Parse Output
+
+- Extract: testContextPath (`.workflow/active/[sessionId]/.process/test-context-package.json`)
+
+**Validation**:
+- test-context-package.json exists and is valid JSON
+- Contains framework detection results
+
+### TodoWrite Update (Phase 3 Skill executed - tasks attached)
+
+```json
+[
+  {"content": "Phase 1: Session Discovery", "status": "completed", "activeForm": "Executing session discovery"},
+  {"content": "Phase 2: Context Gathering", "status": "completed", "activeForm": "Executing context gathering"},

+]
+```
+
+**Note**: Skill execute **attaches** test-context-gather's 3 tasks. Orchestrator **executes** these tasks.
+
+**Next Action**: Tasks attached → **Execute Phase 3.1-3.3** sequentially
+
+### TodoWrite Update (Phase 3 completed - tasks collapsed)
+
+```json
+[
+  {"content": "Phase 1: Session Discovery", "status": "completed", "activeForm": "Executing session discovery"},
+  {"content": "Phase 2: Context Gathering", "status": "completed", "activeForm": "Executing context gathering"},
+  {"content": "Phase 3: Test Coverage Analysis", "status": "completed", "activeForm": "Executing test coverage analysis"},
+  {"content": "Phase 5: TDD Task Generation", "status": "pending", "activeForm": "Executing TDD task generation"},
+  {"content": "Phase 6: TDD Structure Validation", "status": "pending", "activeForm": "Validating TDD structure"}
+]
+```
+
+**Note**: Phase 3 tasks completed and collapsed to summary.
+
+**After Phase 3**: Return to user showing test coverage results, then auto-continue to Phase 4/5 (depending on conflict_risk)
+
+## Output
+
+- **Variable**: `testContextPath` (path to test-context-package.json)
+- **TodoWrite**: Mark Phase 3 completed
+
+## Next Phase
+
+Based on `conflictRisk` from Phase 2:
+- If conflictRisk ≥ medium → [Phase 4: Conflict Resolution](04-conflict-resolution.md)
+- If conflictRisk < medium → Skip to [Phase 5: TDD Task Generation](05-tdd-task-generation.md)
