clippy's items_after_test_module fired on schema.rs: the new migration
const was appended to the end of the file, which is after the
#[cfg(test)] block added alongside migration 024.
error: items after a test module
--> src/storage/schema.rs:901:1
Only visible under --all-targets, which compiles the test target; the
--lib run I checked locally cannot see it. CI runs --all-targets, so it
failed there and nowhere else. Verified this time with the exact CI
invocation rather than a narrower one.
