// SonicForge App Logger — ghi hành động quan trọng của client (console + POST
// /api/v1/logs để server log). Fire-and-forget: không throw, không block UI.
// Các category dùng chung:
//   INSTRUMENT  — lỗi load instrument (soundfont select/load fail)
//   VSTI        — VSTi load/autosample/preview fail
//   MIDI_ITEM   — MIDI item qua mastering fx chain / main out (playback)
//   DRAG_MIDI   — lỗi drag MIDI từ MEDIA EXPLORER hoặc window explorer
