fix: resolve dmap profiling issues and optimize profiling speed

Fixed multiple issues preventing dmap from being profiled correctly:
- Updated profile_dmap.sh to use DTail default log format
- Fixed MapReduce queries to use correct field syntax
- Reduced file sizes and run counts for faster profiling
- Added proper command echoing to all data generation steps

Optimizations:
- Reduced PROFILE_RUNS from 3 to 1
- Reduced test data sizes (1MB/10MB instead of 10MB/100MB/1GB)
- Commented out medium/large file tests for faster runs
- Reduced dmap test data from 1000/10000 to 100/1000 lines

The profiling framework now successfully profiles all three commands
(dcat, dgrep, dmap) with reasonable execution times.
