T5: unified MIDI routing - thay native preview bang UnifiedMidiRouter + TrackInstrument (per-track FluidSynth channel); keybed/click/draw/hardware MIDI note qua router, fallback SonicSF; _panicMidi stop moi voice; bo _nativeSfPreviews/playNativeSfNote/stopNativeSfNote/stopAllNativeSfNotes/_sfWasmFallbackNote

+// SonicForge TrackInstrument Service
+// Bọc FluidSynth channel per-track: playNote/noteOff theo TrackInstrumentCtx
+// (ch/program/synthEngine/sfId/bank/prog/dest) — dùng cho preview mọi nguồn
+// (keybed, piano roll, draw, hardware MIDI, click) qua UnifiedMidiRouter.
+// Tạo mới mỗi note-on (overwrite registry) — voice cũ giữ engine cũ trong
+// tracker nên note-off luôn stop đúng channel.
