feat: convert lite-plan and multi-cli-plan commands to orchestrator+phases skills

Convert workflow commands to unified skill structure with thin router pattern:
- workflow-lite-plan: routes lite-plan + lite-execute with prompt enhancement
- workflow-multi-cli-plan: routes multi-cli-plan + lite-execute with prompt enhancement
Both preserve original command content verbatim in phase files.

+# Workflow Lite-Plan
+
+Unified lightweight planning and execution skill. Routes to lite-plan (planning pipeline) or lite-execute (execution engine) based on trigger, with prompt enhancement for both modes.
+
+## Architecture Overview
+
+```
+┌─────────────────────────────────────────────────────┐
+│  SKILL.md (Router + Prompt Enhancement)              │
+│  → Detect mode → Enhance prompt → Dispatch to phase │
+└──────────────────────┬──────────────────────────────┘
+                       │
+           ┌───────────┼───────────┐
+           ↓                       ↓
+     ┌───────────┐           ┌───────────┐
+     │ lite-plan │           │lite-execute│

+     │ Plan+Exec │──handoff─→│ Standalone │
+     └───────────┘           └───────────┘
+```
+
+## Mode Detection & Routing
+
+```javascript
+const args = $ARGUMENTS
+const mode = detectMode()
+
+function detectMode() {
+  if (skillName === 'workflow:lite-execute') return 'execute'
+  return 'plan'  // default: workflow:lite-plan
+}
+```
+
+**Routing Table**:
+
+| Trigger | Mode | Phase Document | Description |
+|---------|------|----------------|-------------|
+| `workflow:lite-plan` | plan | [phases/01-lite-plan.md](phases/01-lite-plan.md) | Full planning pipeline (explore → plan → confirm → execute) |
+| `workflow:lite-execute` | execute | [phases/02-lite-execute.md](phases/02-lite-execute.md) | Standalone execution (in-memory / prompt / file) |
+
+## Prompt Enhancement
+
+Before dispatching to the target phase, enhance context:
+
+```javascript
+// Step 1: Check for project context files
+const hasProjectTech = fileExists('.workflow/project-tech.json')
+const hasProjectGuidelines = fileExists('.workflow/project-guidelines.json')
+
+// Step 2: Log available context
+if (hasProjectTech) {
+  console.log('Project tech context available: .workflow/project-tech.json')
+}
+if (hasProjectGuidelines) {
+  console.log('Project guidelines available: .workflow/project-guidelines.json')
+}
+
+// Step 3: Dispatch to phase
+if (mode === 'plan') {
+  // Read phases/01-lite-plan.md and execute
+} else {
+  // Read phases/02-lite-execute.md and execute
+}
+```
+
+## Execution Flow
+
+### Plan Mode (workflow:lite-plan)
+
+```
+1. Parse flags (-y/--yes, -e/--explore) and task description
+2. Enhance prompt with project context availability
+3. Read phases/01-lite-plan.md
+4. Execute lite-plan pipeline (Phase 1-5 within the phase doc)
+5. lite-plan Phase 5 internally calls workflow:lite-execute via Skill handoff
+```
+
+### Execute Mode (workflow:lite-execute)
+
+```
+1. Parse flags (--in-memory, -y/--yes) and input
+2. Enhance prompt with project context availability
+3. Read phases/02-lite-execute.md
+4. Execute lite-execute pipeline (input detection → execution → review)
+```
+
+## Usage
+
+```bash
+# Plan mode
+/workflow:lite-plan "实现JWT认证"                    # Interactive
+/workflow:lite-plan --yes "实现JWT认证"              # Auto mode
+/workflow:lite-plan -y -e "优化数据库查询性能"       # Auto + force exploration
+
+# Execute mode (standalone)
+/workflow:lite-execute "Add unit tests for auth"     # Prompt description
+/workflow:lite-execute plan.json                     # File input
+/workflow:lite-execute --in-memory                   # Called by lite-plan internally
+```

+## Phase Reference Documents
+
+| Phase | Document | Purpose |
+|-------|----------|---------|
+| 1 | [phases/01-lite-plan.md](phases/01-lite-plan.md) | Complete planning pipeline: exploration, clarification, planning, confirmation, handoff |
+| 2 | [phases/02-lite-execute.md](phases/02-lite-execute.md) | Complete execution engine: input modes, task grouping, batch execution, code review |
