// Offline FX render mode (Phase 0 of PLAN_MASTERBUS_FX_RACK_VST.md):
// `daw_vst_bridge --render-fx <job.json> --in <input.wav> --out <output.wav>`
// reads a stereo WAV, runs the input through a chain of VST3 audio effects
// (audio-in/audio-out, NO MIDI) plus builtin DSP (gain/normalize), and writes
// a 16-bit stereo WAV. Same exit-code contract as --render: 0 ok, 1 job/argument
// error, 2 plugin load failure, 3 plugin crashed mid-render (SEH guarded).
//
// job.json: { sample_rate, block_size?,
//             fx_chain: [
//               { type: "vst3", path, preset_b64?, bypass? },

//   vst3: path = .vst3 module; preset_b64 = base64 of a .vstpreset FILE (raw
//         SDK chunk format) or of the bridge state blob — both applied via
//         setState before processing. bypass=true → slot skipped (passthrough).
//   gain: multiply by 10^(db/20), block-wise.
//   normalize: post-chain global pass — scale down to peak (0.95) only when
//         the peak EXCEEDS it (mirrors render_project's clip guard).

//   {"plugins":[{"path":"...","name":"...","is_fx":true,"is_instrument":false,"type":"VST3"}]}
// .dll/.so (VST2) cannot be introspected headlessly → classified as instrument.

// Windows only. Exit codes: 0 ok, 1 job/argument error, 2 plugin load or
