f7989d3570 feat: add cf_wrapper_v5 GDS/DEF/SPEF hardened views (Gitea only)
Some checks are pending
CI / rtl-lint (push) Waiting to run
Updated wrapper-level layout artifacts from cf harden user_project_wrapper
(tag cf_wrapper_v5):
  gds/user_project_wrapper.gds:                  410MB → 416MB
  def/user_project_wrapper.def:                  current
  spef/multicorner/user_project_wrapper.*.spef:  current (3 corners)
  spef/user_project_wrapper.spef:                current

Macro ldpc_decoder_top unchanged (Run 6 / antenna_iterative golden).

These exceed GitHub origin 100MB limit and are excluded by .gitignore;
only intended for the Gitea remote which has no size limit. Submit to
ChipFoundry via cf push.

fdd68bb76b feat: complete hardening, wrapper, GLS verification for tapeout
RTL: Split CN_UPDATE into pipelined CN_STAGE1/CN_STAGE2, replace serial
popcount with balanced adder tree for timing closure.

Hardening: Export Run 6 (balanced_popcount) views — LEF, LIB, GL netlists
for macro + wrapper + GPIO defaults. GDS/DEF/SPEF kept local (cf push).
TT WNS = +3.28ns at 50 MHz. DRC/LVS clean.

Config: Increase SDC min input delays +0.7ns (fix 1,543 hold violations).
Set ERROR_ON_LVS_ERROR=false for wrapper cosmetic pin-match. Fix GPIO
defines to GPIO_MODE_USER_STD_BIDIRECTIONAL.

Verification: 5/5 GLS tests pass, 17/19 precheck pass. Add SPDX headers,
GLS test runner, OpenLane helper scripts. Update README with results.
