Enhance profiler to show detailed mask usage for individual operations:
- Track total/false elements per load/store operation
- Display top 5 operations by false elements with line numbers
- Extract and show complete multi-line source code statements
- Add aggregated summary table sorted by mask inefficiency
New utility functions in `clients/utils.py`:
- `extract_complete_statement_from_line()`: Parse multi-line Python statements
- `get_source_location_from_stack()`: Extract user code location from call stack
Example output:
```
Total elements: 67,108,864
False elements: 29,360,128 (43.8%)
Code:
src_data = tl.load(...)
```
