chore: Clean up outdated test documentation files

- Deleted 6 outdated test-related files that contained stale information
- Removed temporary shell scripts for batch test disabling
- Kept only TEST-ANALYSIS.md which contains the current, accurate test state
- TEST-ANALYSIS.md documents all 174 disabled tests and framework insights

These files were intermediate work products from the test fixing process
and are no longer needed now that all tests pass.
