refactor(bridge): split fx bridge, stabilize VST3 host chain, drop old install engines

- remove diagnostic canaries from audio hot path (crackle fix) and stuck C5 note raw-MIDI test (Vst2Instrument::init noteOff) - split native bridge into daw_vst_bridge (VSTi) + fx_vst_bridge (VST FX) - VST3: processData prepare before setActive, zero input buses, accept both .vstpreset and bridge-state blob in RenderJob presets - native_render/vst_engine: bridge-exe discovery + render_fx_chain + /fx-gui - delete old install/ engine binaries (install via sidecar+resources now) - add BUILD_LAYOUT.md, build_selfcheck, tools/ diagnostics
