Phase 2.1: Merged Path00+Path01 NTT engine. - barrett_mul.v: Barrett modular multiplication (a·b mod 3329) - butterfly_unit.v: Cooley-Tukey/Gentleman-Sande butterfly - zeta_rom.v: 128-entry ROM with bit-reversed roots of unity - ntt_core.v: 7-layer NTT FSM, 256×12-bit register file - ntt_sync.v: valid/ready streaming wrapper Verified: 13/13 vectors bit-exact vs Python NTT/NTTInverse
