feat(retrieval): add CAM retrieval benchmark with topk scoring and read noise support

Browse Source

- Add cocotb benchmark infrastructure under hw/sim/benchmarks/retrieval/ with Makefile
- Implement test_retrieval_benchmark.py supporting configurable topk-k, read/write noise
- Add cluster-based synthetic dataset generator with configurable bit-flip rates
- Add reference model functions: match_topk, match_topk_from_scores, score_rows_with_read_noise
- Add .justfile shortcuts: cam-test-retrieval-no-noise, cam-test-retrieval-read-noise
- Add TOPK_K to Verilator EXTRA_ARGS via cocotb-common.mk
- Add unit tests for topk sorting logic and stateful read-noise scoring
