eslint --fix formatting sweep plus the manual residue: sync method
bodies drop async behind Promise-returning signatures (the sqlite unit
routes primitives through a settle() guard preserving the never-throws-
synchronously contract), catch callbacks type their reason as unknown,
loadAll's global slot is plain unknown (null semantics stay in JSDoc),
a non-null assertion becomes a narrowing, and unsafe any assignments in
tests gain explicit types. One justified eslint-disable for
prefer-promise-reject-errors follows the core/session precedent —
wrapping would discard the original StorageError code.
