Support Qwen Code CLI hooks (same as Gemini CLI integration)

Summary

Qwen Code is an LLM-powered coding assistant with a CLI interface and BeforeTool hook system architecturally very similar to Gemini CLI. This feature request is to add first-class RTK support for Qwen Code.

Current Status

RTK currently supports 10+ AI coding tools:

• ✅ Claude Code
• ✅ GitHub Copilot (VS Code + CLI)
• ✅ Cursor
• ✅ Gemini CLI
• ✅ Cline / Roo Code
• ✅ Windsurf
• ✅ Codex
• ✅ OpenCode
• ✅ OpenClaw
• ⏳ Mistral Vibe (planned)

Qwen Code is missing from this list.

Why Qwen Code?

Qwen Code is gaining adoption as a powerful open-source alternative to Claude Code and Copilot. Users would benefit from RTK's 60-90% token savings just like other supported agents.

Technical Feasibility

JSON Format Similarity to Gemini CLI

Qwen Code BeforeTool Input:

{
  "tool_name": "run_shell_command",
  "tool_input": { "command": "git status" }
}

Expected RTK Output:

{
  "decision": "allow",
  "hookSpecificOutput": {
    "tool_input": { "command": "rtk git status" }
  }
}

This is virtually identical to Gemini CLI's hook format (see hooks/README.md#Gemini-CLI).

Implementation Effort

Minimal — RTK already has:

1. ✅ Command rewrite logic (src/discover/registry.rs) — reusable
2. ✅ Gemini CLI handler (src/hooks/hook_cmd.rs::run_gemini()) — can be reused or slightly adapted
3. ✅ Settings.json patching (src/hooks/init.rs::patch_gemini_settings()) — template exists
4. ✅ Installation CLI (rtk init -g --gemini) — pattern established

Proposal: Add rtk init -g --qwen command that:

• Creates ~/.qwen/hooks/rtk-rewrite.sh (or similar)
• Patches ~/.qwen/settings.json with BeforeTool hook entry
• Installs QWEN.md (RTK awareness doc)

This is a straightforward extension of the existing Gemini CLI support.

Expected Outcome

After implementation, users can:

# 1. Install RTK for Qwen Code
rtk init -g --qwen

# 2. Restart Qwen Code

# 3. Commands auto-rewrite transparently
git status       # → internally: rtk git status
cargo test       # → internally: rtk cargo test
npm list         # → internally: rtk npm list
# etc. (all 100+ supported commands)

# 4. Check savings
rtk gain

I'm happy to:

• ✅ Test early builds on Qwen Code
• ✅ Provide hook API documentation if available
• ✅ Contribute a PR if you want community implementation

Thanks for the amazing RTK project! 🚀
