Show and tell: DSBrain (macOS menu bar for ds4-server)

## Show and tell: DSBrain

Small companion app for people running `ds4-server` on macOS (Apple Silicon).

**Repo:** https://github.com/derkan/dsbrain

It sits in the menu bar and:
- starts / adopts / restarts a local `ds4-server`
- shows live tray metrics from server logs (P/T tk/s, context, SSD hit, GPU/MEM, fans)
- optional fan rules via SMC
- one-click open project folders with Pi / Codex / Cursor against the local OpenAI-compatible endpoint

Install: `brew tap derkan/dsbrain https://github.com/derkan/dsbrain && brew trust derkan/dsbrain && brew install --cask dsbrain`
