fix(fx-rt): burst 4-block input batch qua bridge — hết lag/giật/crackle master FX
- worklet gom 1024 mẫu (4 block) vào 1 frame interleaved, main thread tách 4 WS frame 512 floats
- bridge take=min(avail,4) xử lí 1 call process cho burst → overhead VST3 amortize 4 lần
- engine _pump_output pace theo deadline thay vì sleep cố định (outRead 131→187.5/s)
- FX_RT_ROUNDTRIP_SAMPLES 512→1792 (RTT batching ~7 block)

Phase 2: BuiltinFxChain C++ (8 DSP) + control ring SET_PARAM/REPORT_LATENCY
- native_bridge/src/BuiltinFxChain.{h,cpp}: 8 builtin DSP port 1:1 từ
Python _apply_builtin_fx_chain (eq/eqpro/compressor/limiter/exciter/rebalance)
và JS MASTER_MODULE_IO (imager/maximizer). Biquad RBJ DF2T, block-wise
stateful. createBuiltinFx trả nullptr cho gain/normalize (legacy).
- RenderFxJob: FxSlot thêm bfx, parse builtin 8 loại, runBuiltinSlotSafe SEH,
realtimeRunChain nhánh builtin, chainGen()/entryLatencies(), setParam
áp live lên bfx; Vst3Fx latencySamples từ getLatencySamples().
- RealtimeFxLoop: drain ctrl ring (SET_PARAM -> chain.setParam, drop cũ khi
đầy) + REPORT_LATENCY khi gen đổi (ipc->lat[] ring, lastGen).
- FxRealtimeIPC.h: header 18 u32 (72B), ctrl/lat slots 8, FxCtrlCmd 24B,
FxLatReport 8B, static_asserts.
- app/core/fx_realtime.py: mirror header 72B (ctrl_write/read, lat_write/read,
slots), set_param ghi ctrl ring qua _ctrl_enqueue_locked (guard shm),
get_latencies drain lat ring qua _lat_drain.
- tests/test_builtin_fx_golden.py: golden SNR C++ vs Python (8 cases, ngưỡng
30dB) + order test eq/compressor xen kẽ.
- TASKS_DAW_A.md: tick 2.1-2.9.
Test: 136 passed (4 fx_realtime_chain + 8 builtin golden + regression).
