feat: Redesign test-gen workflow with independent session and cross-session context

Major redesign of test-gen workflow based on simplified architecture:

Core Changes:
- Creates independent test session (WFS-test-[source]) instead of modifying existing session
- Implements 4-phase execution with concept-enhanced analysis integration
- Reuses IMPL-*.json format with meta.type="test-fix" (no new task type)
- Auto-detects cross-session context via workflow-session.json metadata

4-Phase Workflow:
1. Phase 1: Create test session with workflow_type and source_session_id metadata
2. Phase 2: Auto-detect and gather cross-session context (summaries, git changes, tests)
3. Phase 3: Analyze implementation with concept-enhanced (parallel Gemini + Codex)
4. Phase 4: Generate IMPL-001.json task with test strategy from ANALYSIS_RESULTS.md

Key Features:
- Session isolation: Test session separate from implementation session
- Parameter simplification: context-gather auto-detects via metadata (no --source-session param)
- Format reuse: IMPL-*.json with meta.type field (zero changes to execute/status tools)
- Analysis integration: concept-enhanced provides comprehensive test strategy and code targets
- Automatic cross-session: Collects source session artifacts automatically

Tool Modifications Required:
- session-start: Support test session metadata (workflow_type, source_session_id)
- context-gather: Auto-detect test session and gather from source session
- task-generate: Extract test strategy from ANALYSIS_RESULTS.md
- concept-enhanced: No changes (already supports analysis)
- execute: No changes (already dispatches by meta.agent)

Data Flow:
User → session-start (creates test session) → context-gather (auto cross-session)
→ concept-enhanced (analyzes + generates strategy) → task-generate (creates task)
→ Returns summary → User triggers /workflow:execute separately

 ## Coordinator Role
 
-**This command is a pure orchestrator**: Analyze completed implementation session, generate test-fix workflow through standardized tool commands, and trigger automated test validation.
+**This command is a pure orchestrator**: Creates an independent test-fix workflow session for validating a completed implementation. It reuses the standard planning toolchain with automatic cross-session context gathering.
+
+**Core Principles**:
+- **Session Isolation**: Creates new `WFS-test-[source]` session to keep verification separate from implementation
+- **Context-First**: Prioritizes gathering code changes and summaries from source session
+- **Format Reuse**: Creates standard `IMPL-*.json` task, using `meta.type: "test-fix"` for agent assignment
+- **Parameter Simplification**: Tools auto-detect test session type via metadata, no manual cross-session parameters needed
 
 **Execution Flow**:
-1. Initialize TodoWrite → Execute Phase 1 → Parse output → Update TodoWrite
-2. Execute Phase 2 with Phase 1 data → Parse output → Update TodoWrite
-3. Execute Phase 3 with Phase 2 data → Parse output → Update TodoWrite
-4. Execute Phase 4 with Phase 3 validation → Update TodoWrite → Return summary
+1. Initialize TodoWrite → Create test session → Parse session ID
+2. Gather cross-session context (automatic) → Parse context path
+3. Analyze implementation with concept-enhanced → Parse ANALYSIS_RESULTS.md
+4. Generate test task from analysis → Return summary
 
 ## Core Rules
 
-1. **Start Immediately**: First action is TodoWrite initialization, second action is Phase 1 session discovery
+1. **Start Immediately**: First action is TodoWrite initialization, second action is Phase 1 test session creation
 2. **No Preliminary Analysis**: Do not read files or analyze before Phase 1
 3. **Parse Every Output**: Extract required data from each phase for next phase
 4. **Sequential Execution**: Each phase depends on previous phase's output
-5. **Complete All Phases**: Do not return to user until Phase 4 completes
+5. **Complete All Phases**: Do not return to user until Phase 4 completes (execution triggered separately)
 6. **Track Progress**: Update TodoWrite after every phase completion
-7. **Use Standard Tools**: Follow plan.md pattern using context-gather, concept-enhanced, task-generate
+7. **Automatic Detection**: context-gather auto-detects test session and gathers source session context
 
 ## 4-Phase Execution
 
-### Phase 1: Session Discovery & Context Gathering
-**Command**: `SlashCommand(command="/workflow:tools:context-gather --session [sessionId] \"TEST-FIX: Validate implementation for [sessionId]\"")`
+### Phase 1: Create Test Session
+**Command**: `SlashCommand(command="/workflow:session:start --new \"Test validation for [sourceSessionId]\"")`
 
-**Session ID Resolution**:
-- If argument provided → Use directly as `sessionId`
-- If no argument → Auto-detect from `.workflow/.active-*` marker
-- Format: `WFS-[session-name]`
+**Input**: `sourceSessionId` from user argument (e.g., `WFS-user-auth`)
 
-**Task Description Structure**:
-```
-GOAL: Execute and validate all tests for completed implementation
-SCOPE: Test execution, failure diagnosis, code fixing
-CONTEXT: Implementation session [sessionId] with completed IMPL tasks
-```
+**Expected Behavior**:
+- Creates new session with pattern `WFS-test-[source-slug]` (e.g., `WFS-test-user-auth`)
+- Writes metadata to `workflow-session.json`:
+  - `workflow_type: "test_session"`
+  - `source_session_id: "[sourceSessionId]"`
+- Returns new session ID for subsequent phases
 
 **Parse Output**:
-- Extract: context package path (store as `contextPath`)
-- Typical pattern: `.workflow/[sessionId]/.process/context-package-test.json`
+- Extract: new test session ID (store as `testSessionId`)
+- Pattern: `WFS-test-[slug]`
 
 **Validation**:
-- Session directory `.workflow/[sessionId]/` exists
-- Session has completed IMPL tasks (check .summaries/IMPL-*-summary.md)
-- Context package created successfully
+- Source session `.workflow/[sourceSessionId]/` exists
+- Source session has completed IMPL tasks (`.summaries/IMPL-*-summary.md`)
+- New test session directory created
+- Metadata includes `workflow_type` and `source_session_id`

-**Input**: `sessionId` from Phase 1, `contextPath` from Phase 1
+**Input**: `testSessionId` from Phase 1 (e.g., `WFS-test-user-auth`)
 
-**Expected Analysis**:
-- Review completed implementation summaries
-- Identify test files and coverage gaps
-- Assess test execution strategy
-- Determine failure diagnosis approach
+**Automatic Detection**:
+- context-gather reads `.workflow/[testSessionId]/workflow-session.json`
+- Detects `workflow_type: "test_session"`
+- Automatically uses `source_session_id` to gather source session context
+- No need for manual `--source-session` parameter
+
+**Cross-Session Context Collection** (Automatic):
+- Implementation summaries: `.workflow/[sourceSessionId]/.summaries/IMPL-*-summary.md`
+- Code changes: `git log --since=[source_session_created_at]` for changed files
+- Original plan: `.workflow/[sourceSessionId]/IMPL_PLAN.md`
+- Test files: Discovered via MCP code-index tools
 
 **Parse Output**:
-- Verify `.workflow/[sessionId]/.process/ANALYSIS_RESULTS.md` created
-- Extract test execution recommendations
-- Identify critical test areas
+- Extract: context package path (store as `contextPath`)
+- Pattern: `.workflow/[testSessionId]/.process/context-package.json`
 
 **Validation**:
-- File `.workflow/[sessionId]/.process/ANALYSIS_RESULTS.md` exists
-- Contains test strategy and execution plan
-- Lists focus test paths and acceptance criteria
+- Context package created in test session directory
+- Contains source session artifacts (summaries, changed files)

 ## Best Practices
 
-1. **Run after implementation complete**: Ensure all IMPL tasks are done before test-gen
-2. **Check git commits**: Make sure implementation changes are committed
-3. **Verify test files exist**: Code-developer should have created tests
-4. **Monitor execution**: Use `/workflow:status` to track test-fix progress
-5. **Review failures**: If tests fail repeatedly, check test-fix-agent summary for details
+1. **Run after implementation complete**: Ensure source session has completed IMPL tasks and summaries
+2. **Check git commits**: Implementation changes should be committed for accurate git log analysis
+3. **Verify test files exist**: Source implementation should include test files
+4. **Independent sessions**: Test session is separate from implementation session for clean separation
+5. **Monitor execution**: Use `/workflow:status` to track test-fix progress after /workflow:execute
 
 ## Coordinator Checklist
 
-✅ Initialize TodoWrite before any command
-✅ Execute Phase 1 immediately with session ID
-✅ Parse context package path from Phase 1 output
-✅ Pass session ID and context path to Phase 2 command
-✅ Verify ANALYSIS_RESULTS.md after Phase 2
-✅ Pass session ID to Phase 3 command
-✅ Verify all Phase 3 outputs (task JSON, IMPL_PLAN, TODO_LIST)
-✅ Pass session ID to Phase 4 command
+✅ Initialize TodoWrite before any command (4 phases)
+✅ Phase 1: Create test session with source session ID
+✅ Parse new test session ID from Phase 1 output
+✅ Phase 2: Run context-gather (auto-detects test session, no extra params)
+✅ Verify context-package.json contains cross-session artifacts
+✅ Phase 3: Run concept-enhanced with session and context path
+✅ Verify ANALYSIS_RESULTS.md contains test strategy and code targets
+✅ Phase 4: Run task-generate to create IMPL-001.json
+✅ Verify task has meta.type="test-fix" and meta.agent="@test-fix-agent"
