refactor: reorganize RTL files into core/noise subdirectories

- Move CAM core modules (cam_core_banked, match_engine_pipeline, popcount_pipeline) to hw/rtl/core/
- Move noise modules (cam_read_noise, cam_write_noise, noise_mask_grouped) to hw/rtl/noise/
- Update Makefile include paths and VERILOG_SOURCES to reflect new layout
- Update docs/experiments.md file path references
- Add sim/results.xml to .gitignore
- Bump devenv.lock dependencies
