cah 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.
