- Fix W293 trailing whitespace in tool.py line 249
- Fix typecheck error in session_service.py: data.get("checksum")

type annotation for wrapper variable to resolve str|None issue
- Fix vulture false positive: add "destination" Protocol parameter
to vulture_whitelist.py
- Fix @tdd_issue/@tdd_issue_1472 tag placement in skill_schema.feature
