release: v0.1.22

- Remove hardcoded homebrew paths
- Remove npm package path resolution (prone to placeholder issues)
- Only check cached binary (~/.cache/oh-my-opencode/bin/sg)
- If not found, cli.ts will auto-download from GitHub releases

The download logic in cli.ts handles all cases properly.
