Detailed Description

Quantized capture and bounded repeat gestures over FreezeLoopSamplerT.

Capture timing is lowered from CompiledTempoMap and the canonical BeatDivision tick lattice. The kernel therefore has no independent BPM or floating-point transport clock. It records dry input only, captures an exact recent interval without clamping, and layers finite/infinite repeat, gate, reverse, seek, retrigger, and click-safe transitions over the reused sampler storage.

RT contract: prepare(), snapshot(), and restore() may allocate. After a successful prepare(), trigger(), stop(), seek(), reset(), transport_discontinuity(), parameter setters, and process() allocate nothing and take no locks.
