fix: improve resource trackers and fix tests

bhouston · bhouston · commit c31546ea0375 · 2025-03-18T11:10:37.000-04:00
- Standardize file naming by renaming ShellTracker.ts to shellTracker.ts
- Fix tests to use toolContext.shellTracker instead of local instances
- Update test assertions to work with the new tracker structure
- Fix test for piped commands to be more reliable
