Details
harden: regenerate user_project_wrapper via cf harden (cf_wrapper_v5) 
Re-hardened wrapper with chipfoundry-cli (LibreLane) per contest item #3.
Macro ldpc_decoder_top unchanged (Run 6 / antenna_iterative golden) —
wrapper config has SYNTH_ELABORATE_ONLY=true and reuses macro as a
hardened black box.

Results vs wrapper_v4 baseline:
  setup violations:    3402 → 0
  hold violations:    13006 → 0
  antenna nets:        1179 → 23
  Magic + KLayout DRC: clean
  power-grid:          clean
  LVS pin-match:       208 (cosmetic, vssd2 + constant-tied outputs)

Verification:
  cf precheck:                    17/19 pass (FEOL SIGSEGV + LVS pin-match
                                  pre-existing accepted)
  cf verify ldpc_basic --sim gl:  PASS (GPIO=0xAB, decode success)

GDS/DEF/SPEF kept local for cf push.
