fix: resolve all clippy -D warnings failures

- core/utils.rs: remove unreachable thread::sleep + attempt increment after
  a match where every arm diverges (return/continue/exit)
- commands/base.rs: annotate run_callback with #[allow(clippy::too_many_arguments)]
  (pre-existing 10-param signature; refactor is out of scope here)
- core/templating.rs: introduce SqlQueriesResult type alias to satisfy
  clippy::type_complexity on load_sql_queries return type
