Ein Anderssono 6fd2d8d883 Add detailed profiling system for execution time breakdown
- Create profile_detailed.sh script for measuring startup, calculation, and I/O time
- Add PROFILING.md documentation explaining the profiling system
- Measure startup time (runtime initialization, library loading)
- Measure calculation time (algorithm execution)
- Estimate I/O time (output formatting)
- Support all compiled, JIT, and interpreted languages
