refactor: move profiling scripts from benchmarks/ to profiling/

- Moved profile_benchmarks.sh, profile_dmap.sh, and profile_quick.sh
  to the profiling/ directory where they belong
- Updated Makefile targets to reference new locations
- Fixed profile_dmap.sh to remove outfile clauses since they're not
  needed for profiling and were preventing proper execution
- Updated .gitignore to exclude generated files in profiling/

This better separates benchmarking (performance comparison) from
profiling (performance analysis).
