JamesandClaude Opus 4.6 15f6b86ac0 feat(render): add WebM output with VP9 alpha transparency ...

Support rendering compositions with transparent backgrounds via
`--format webm`. VP9+alpha is the standard format for overlayable
video (captions, lower thirds, overlays).

Changes by layer:
- CLI: `--format mp4|webm` flag on render command
- Producer: threads format through RenderConfig, switches to PNG
  capture and VP9 encoding when webm
- Engine: getEncoderPreset() returns VP9 config with yuva420p;
  transparent page background via CDP when capturing PNG;
  mux uses Opus audio for WebM; VP9 flags from production:
  -row-mt 1, -auto-alt-ref 0, alpha_mode=1 metadata
- Frame capture: Emulation.setDefaultBackgroundColorOverride a=0
