feat(tb): add KAT testbench for mlkem_top (ML-KEM-512)

- gen_vectors.py: parse kat_MLKEM_512.rsp, generate hex vectors
- tb_mlkem_top_xsim.v: force-inject d/msg/z for KAT testing
- mlkem_top_input.hex: 5 vectors (d + msg + z)
- mlkem_top_expected.hex: 5 vectors (pk + sk + ct + ss)
- xsim_run.tcl: full dependency chain compilation

Known issue: mlkem_top FSM has combinational race on rng_valid_i
- rng_valid_i driven by state_r (registered) causes rng_sync
  to miss valid_i pulse when state transitions at posedge
- Fix: change rng_valid_i to use state_next pattern
  (same as sha3_top uses state_next for kc_valid_i)

feat(top): add shared keccak variants, arbiter, and mlkem_top integration

- sha3_chain_top_shared.v: external keccak_core interface (6 ports)
- sample_cbd_sync_shared.v: shared keccak variant (6 ports)
- sample_ntt_sync_shared.v: shared keccak variant (6 ports)
- keccak_arbiter.v: fixed-priority arbiter for 3 keccak consumers
- mlkem_top.v: 1403-line monolithic FSM with KeyGen/Encaps/Decaps

Architecture:
  keccak_arbiter → keccak_core → keccak_round (shared)
  sha3_chain_top_shared (consumer 0)
  sample_cbd_sync_shared (consumer 1)
  sample_ntt_sync_shared (consumer 2)
  sha3_top (separate, own keccak_core)
  rng_sync, ntt_core, poly_arith, poly_mul, comp_decomp, mod_add
  sd_bram for polynomial storage

All original RTL files preserved unchanged.
