Add mmjproj projector sidecar support

- Recognize mmjproj as a projector marker alongside mmproj, vision-adapter, projector
- Score mmjproj candidates in sidecar auto-download selection
- Broaden user-facing projector readiness message to mmproj/mmjproj
- Add unit tests for mmjproj filtering and case-insensitive detection
