BREAKING CHANGE: CAM write and query interface replaced with standard valid/ready handshake. wr_en/wr_row/wr_hash → wr_valid/wr_ready/wr_addr/write_hash. External noise_mask_lanes_flat removed; noise generation now handled internally by cam_noisy module with configurable rate via parameters. - cam_top: add parameters (NOISE_EN, NOISE_RATE_NUM/DEN, NOISE_GEN/SAMPLE_BITS, NOISE_SEED) - cam_top: replace cam_core with cam_noisy (integrated noise generation) - match_engine: remove external noise_mask_lanes_flat input - hw/sim: update Makefile with noise parameters and compile args - hw/sim/model: add generate_write_flip_mask() and xorshift64() matching RTL behavior - hw/sim/tests: adapt testbench to new handshake protocol
