test(gate): accept fact/other chunks — validate data chunk ends at EOF

sf.write() float32 WAVs carry a fact chunk; strict 44+data_size check was
too narrow. Walk chunks instead; bridge header bug (half data_size) still
caught because its data chunk must run to EOF.

fix(bridge): WAV header data_size for IEEE float32 (was 16-bit byte count)

- finishWav call sites accumulated n*4 (stereo 16-bit) but float32 writer
  emits n*8 bytes -> RIFF/data chunk sizes half the real value; players and
  soundfile truncated renders to half length
- gate test now asserts file size == 44 + data_size to catch this

Normalize Linux audio pipeline to lossless Float32 (skill: lossless-audio-compliance)

- native bridge WAV writers: 16-bit PCM truncation -> IEEE Float32 (fmt 3, bit-exact)
- vendor sheredom_json.h (vst3sdk 3.8.1 lacks moduleinfo/json.h)
- Dockerfile: drop nonexistent sfizz tag v1.2.3
- Python sf.write -> subtype=FLOAT everywhere
- resample_poly -> kaiser(16) window (>=130dB stopband)
- audio_editor._write_wav_lossless(): FLOAT passthrough, TPDF dither only for
  8/16/24-bit final exports
- app.jsx WAV encoders: Float32 default, TPDF dither for integer depths, fix 24-bit
- tests: lossless compliance gate (null test < -140dBFS, float32 format) 9/9 pass
- TASKS_WINDOWS_AUDIO_NORMALIZE.md: Windows-side remaining tasks
