Initial commit: qwen delegation MCP server, tracker setup, research

- qwen_delegate MCP tool: src/qwen-delegate.ts (testable core, subprocess
  spawn/timeout/parse) + src/qwen-delegate-server.ts (thin MCP stdio wiring)
- test/qwen-delegate.test.ts (node:test, mocked spawn)
- docs/agents/* + CLAUDE.md from /setup-matt-pocock-skills (Gitea issue
  tracker via tea CLI, default triage labels, single-context domain docs)
- research/qwen-mcp-delegation.md, corrected after confirming qwen-code
  runs natively on Windows (no WSL) against a local OpenAI-compatible proxy
