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.
