admin 0cca84c5f9 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.
