Lead fix, folded in. The previous repair accepted any `#[cfg(test)]` item whose
first line ended in `{`, which is the same latch in another spelling: a
semicolon-terminated `static` or `const` can open a block initializer there and
close with `};`, so the exemption ran past it into the next function. Verified
by reverting the condition — the scanner returned no offender at all for a
`std::fs::write` in the function following a `LazyLock` initializer.
Only `mod` and `impl` are accepted as braced shapes, being the two the crate
actually uses. Everything else fails the guard by name rather than being
bounded by a brace that may not be the item's own.
