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

phase4: Linux native_bridge build (Docker) — sfizz from source, --render SF2/SFZ
...
- Dockerfile: build sfizz tu native_bridge/sfizz-src (hoac git clone v1.2.3),
sed fix sfizz.pc (-llibsfizz -> -lsfizz), cmake bridge voi 3 flag SMTG OFF
(VSTGUI/plugin/hosting examples) — bridge headless chi can --render.
- CMakeLists: nhanh non-WIN32 build daw_vst_bridge tu main_linux.cpp +
RenderJob.cpp + NativeInstrumentEngine.cpp (SF2/SF3 + SFZ; VST3/VST2
hosting Windows-only, guard #ifdef _WIN32). gui_probe/plugin_host/
seh_channel_test chi build tren Windows.
- RenderJob.cpp: JSON parser (sheredom json.h) khong con phu thuoc
HAVE_VST3SDK — render SF2/SFZ chay duoc khong can VST3 SDK.
- NativeInstrumentEngine.cpp: guard windows.h/VST3/VST2/Sandbox/SEH.
- main.cpp: g_engine unconditional + guard disable_ime_contexts (_WIN32).
- engine.spec: bo pedalboard collect_dynamic_libs + hidden imports.
- vst_engine/render_engine: DecentSampler -> NotImplementedError + huong
dan convert .dspreset -> .vstpreset; pianobook fallback synth.
- Verified: WSL Ubuntu 24.04 build OK, bridge Linux --render SF2 ra WAV
44100 stereo peak 1575; Python tests 115 passed 1 skipped.
- Dockerfile build chua test duoc (may khong co Docker).

Phase 1: import .vstpreset in offline render (loadSerializedState)
...
daw_vst_bridge --render now applies a VST3 preset when job has 'preset'
(base64 of a .vstpreset file). Parse the SDK binary chunk format with
PresetFile (vst3sdk), rewrap component/controller state into the bridge
blob [4B BE compLen][comp][4B BE ctrlLen][ctrl] and apply via
loadSerializedState before rendering. SF2/SFZ ignore preset (warning).
Bad base64/magic/chunks fail the job with rc 1 and no partial clip.
Tests: golden Nexus .vstpreset fixture; VST3 with/without preset,
bad preset -> rc 1, non-VST3 preset ignored. 20/20 pass.

feat(bridge): add --render offline CLI (Phase 0 of pedalboard replacement)
...
daw_vst_bridge --render <job.json> --out <clip.wav> renders MIDI notes
through the same instrument engines as realtime (SF2/SFZ/VST3/VST2) to a
16-bit stereo WAV, headless, no SHM. Mirrors plugins.py/vst_engine.py
note semantics (velocity int(vel*127), bank CC0 + program at t=0, beatSec
60/max(30,bpm), totalNeeded max(1024,endSample), no tail). Chunk clamped
to 256 to match VST3 host prepared buffers. Uses vendored sheredom json.h
(gated on HAVE_VST3SDK); rc: 0 ok, 1 arg/job error, 2 load fail, 3 crash.
Partial output removed on failure. Verified: SF2, SFZ, Nexus VST3 render
non-silent at exact duration; 9/9 tests pass.
