Miguel Ángel 95d7dc0623 fix(cli): align render output naming and add WebM support to studioServer (#109)
## Summary

- CLI render: use timestamped filenames (`project_date_time.ext`) matching the studio's naming convention, preventing overwrites of previous renders
- studioServer: read `fps`/`quality`/`format` from POST body instead of hardcoding `fps:30`/`quality:standard`/`mp4`
- studioServer: use timestamped job IDs matching the studio pattern
- studioServer: fix download endpoint to serve correct content-type for WebM

## Test plan

- [x] `hyperframes render --format webm` outputs timestamped WebM file
- [x] `hyperframes render` outputs timestamped MP4 (no overwrite)
- [x] Studio embedded server (`hyperframes dev`) renders with correct format when selected in UI
- [x] Download endpoint serves correct MIME type for WebM renders
