Changes:
- Replace grep with awk to handle timestamp lines
- Remove matching commands AND their preceding timestamp lines
- Properly handle history format: #timestamp followed by command
Issue:
- Systems with HISTTIMEFORMAT set store timestamps as #<unix_time>
- Simple grep only removed command lines, left orphaned timestamps
- User's history showed toolkit commands still present (lines 990-1030)
Solution:
- awk script that tracks timestamp lines
- Only prints timestamp if following command is kept
- Removes both timestamp and command together atomically
Tested:
✓ Removes 16 lines (8 commands + 8 timestamps) from 32-line test
✓ Preserves normal commands with their timestamps
✓ No toolkit patterns found after cleaning
