Security vulnerabilities and automated fixes for code quality issues

The SQL helper class in u2share_batch_give_sugar used Python f-strings to construct INSERT and UPDATE queries, creating SQL injection vulnerabilities even though values appeared to come from internal constants. The fix replaces all f-string query construction with sqlite3 parameterized queries using `?` placeholders, eliminating string interpolation entirely from the database path.
A medium-severity vulnerability was recently patched in a Go workflow runtime system where code attempted to iterate over a potentially empty map without proper validation. While this may seem like a minor oversight, such patterns can lead to unexpected behavior, logic bugs, and in some cases, exploitable security vulnerabilities when combined with other code paths.
