feat: Add multi-tool support for CLAUDE.md documentation generation (v3.4.1)

Add flexible tool selection (gemini/qwen/codex) for documentation updates,
allowing users to choose the best tool for their analysis needs.

Changes:
- Add --tool parameter to /update-memory-full and /update-memory-related
- Enhance update_module_claude.sh with tool routing (gemini|qwen|codex)
- Update command documentation with tool selection examples
- Add CHANGELOG entry for v3.4.1

Tool features:
- Gemini (default): Documentation generation, pattern recognition
- Qwen: Architecture analysis, system design (direct command, no wrapper)
- Codex: Implementation validation, code quality analysis

Backward compatible: Commands default to gemini without --tool parameter
