chore: Resolve merge conflict with main (openclaw + qwen + windsurf)

- Combine windsurf scope support from this branch with openclaw/qwen targets from main
- Update resolve-output.ts utility to handle openclaw/qwen with openclawHome/qwenHome/pluginName
- Add openclawHome/qwenHome args to install.ts and convert.ts
- Register openclaw and qwen in targets/index.ts alongside windsurf
- Add openclaw/qwen coverage to resolve-output.test.ts (4 new tests → 288 total)
- Update README to document all 10 targets including windsurf and openclaw
