OUT-2: WebM export (VP9 intra encoder + alpha, Opus), WAV/AIFF audio-only outputs

Browse Source 
- effectcraft-vp9enc (L0): VP9 profile 0 key-frame encoder from the VP9 bitstream spec
  (8x8 intra blocks, DC/V/H/TM, 4x4 DCT/ADST, lossless WHT at quality 100, tile columns);
  round-trips exactly through FilmCraft's VP9 decoder and ffmpeg.
- export: WebM muxer (EBML/Matroska spec) with VP9, VP9 alpha in BlockAdditional
  (AlphaMode 1), Opus (CodecDelay = pre-skip); WAV and AIFF outputs.
- OutputFormat WebM/Wav/Aiff in the Render Queue, renderQueue.add formats, CLI --format.
- Tests: FilmCraft decode-back (frames, size, pixels, audio RMS), ffprobe/ffmpeg oracles.
