Add comprehensive test logging infrastructure to integration tests

- Add test logging infrastructure to track command execution and file comparisons
- Generate .log files for each test with command history and manual verification commands
- Ensure all temporary test files use .tmp suffix for consistency
- Clean up .tmp files before each test run (not after) for clean test starts
- Update .gitignore to exclude generated test artifacts (.log, .query files)
- Fix dserver test configurations to use .tmp suffix for output files
- Fix expected test outputs for dgrep context tests

This change improves test debugging and verification by providing detailed logs
of what each test does and allows manual verification of test results.
