release: v3.3.0 - CLI Tool Enhancements & Codex Multi-Step Execution

✨ Features:
- New /cli:codex-execute command for automated multi-step task execution
- Codex resume mechanism (codex exec "..." resume --last) for context continuity
- TodoWrite progress tracking for subtask execution
- Optional Git verification after each subtask (--verify-git flag)
- Automatic task JSON detection and loading
- Enhanced Codex agent configuration (.codex/AGENTS.md v2.1.0)

📚 Documentation:
- Streamlined CLI documentation (60% reduction in redundancy)
- Updated /cli:analyze, /cli:chat, /cli:execute commands
- Enhanced intelligent-tools-strategy.md with Codex resume patterns
- Unified command templates for Gemini/Qwen vs Codex
- Added Codex -i parameter documentation for image attachment

🔧 Technical:
- Multi-task prompt format (Single-Task & Multi-Task)
- Subtask coordination guidelines and best practices
- Enhanced MODE: auto with subtask execution flow
- Progress reporting for multi-step workflows

📦 Updates:
- Version bumped to 3.3.0 in README.md, README_CN.md
- Created .claude/version.json for version tracking
- Comprehensive CHANGELOG.md entry with all changes

+## Multi-Step Task Execution
+
+### Context Continuity via Resume
+
+When executing subtasks via `codex exec "..." resume --last`:
+
+**Advantages**:
+- Session memory preserves previous decisions
+- Maintains implementation style consistency
+- Avoids redundant context re-injection
+- Enables incremental testing and validation
+
+**Best Practices**:
+1. **First subtask**: Establish patterns and architecture
+2. **Subsequent subtasks**: Build on established patterns
+3. **Test integration**: After each subtask, verify compatibility
+4. **Report context**: Summarize key decisions for next subtask
+5. **Maintain scope**: Focus only on current subtask goals
+
+### Subtask Coordination
+
+**DO**:
+- Remember decisions from previous subtasks
+- Reuse patterns established earlier
+- Test integration with previous work
+- Report what's ready for next subtask
+
+**DON'T**:
+- Re-implement what previous subtasks completed
+- Change patterns established earlier (unless explicitly requested)
+- Skip testing integration points
+- Assume next subtask's requirements
+
+### Example Flow
+
+```
+Subtask 1: Create data models
+→ Establishes: Schema patterns, validation approach
+→ Delivers: Models with tests
+→ Context for next: Model structure, validation rules
+
+Subtask 2: Implement API endpoints (resume --last)
+→ Recalls: Model structure from subtask 1
+→ Builds on: Uses established models
+→ Delivers: API with integration tests
+→ Context for next: API patterns, error handling
+
+Subtask 3: Add authentication (resume --last)
+→ Recalls: API patterns from subtask 2
+→ Integrates: Auth middleware into existing endpoints
+→ Delivers: Secured API
+→ Final validation: Full integration test
+```
