Phase 1: import .vstpreset in offline render (loadSerializedState)

Browse Source 
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.
