- Add hw/syn/Makefile with hier/flat/full synth targets and artifact mirroring - Add synth_cam_top_hier.ys for hierarchy-preserving resource estimation on Xilinx 7-series - Add synth_cam_top_flat.ys for flattened Xilinx 7-series synthesis - Add cam-synth just target for convenient invocation - Guard runtime assertions (NUM_ROWS/LANES checks, noise seed checks, NOISE_BITS checks) behind SYNTHESIS guard in cam_core_banked, cam_read_noise, cam_write_noise, and noise_mask_grouped - Fix shadowed 'return' variable in random128 xorshift128 function
