Style: Final comment cleanup and text refinements

- Removes the unused `TIMEOUT_LONG` constant.
- Adds a blank line after imports for PEP 8 compliance.
- Changes the output heading for overall review bodies from
  "### Summary Comment:" to "### Comment:".
- Performs a final pass to remove extraneous, obsolete, or
  iteration-related comments throughout the script, while retaining
  comments that explain non-obvious logic or important context.
