- Nuovo modulo pm2d/_jit_kernels.py con _jit_score_by_shift Numba njit
parallel + fastmath + boundscheck=False
- Parallelizzazione per riga output (no race condition su acc)
- Fallback automatico numpy se numba non installato
- Warmup automatico al module import (evita JIT lag al 1 match)
Benchmark clip.png (13 istanze):
prima (numpy + threads): 1.55s
dopo (numba + threads): 0.72s
speedup: 2.1x
Pipeline totale full (refine+subpix): 0.80s
