build(dev): switch to ARM64 cross-compile for Pi Zero 2 W deployment

- Rename BINARY_NAME from openclaw to remoterig
- Cross-compile with GOOS=linux GOARCH=arm64 for Raspberry Pi Zero 2 W
- Build React frontend at repo root (npm ci && npm run build) producing dist/
- Remove old web/ working-directory and explicit embed step (handled by go:embed)
- Repository dispatch event_type unchanged: dev-build-success
