Commit Message

Fix sub-module path resolution for lib.rs/main.rs/mod.rs (#1839)

`visit_mod` appended the enclosing file's stem to the child module
path, so `#[cfg(test)] mod tests;` in lib.rs resolved to
src/lib/tests.rs instead of src/tests.rs. The bogus path never matched
the source walker, so the child file escaped the ignore filter and its
non-#[test] items were reported as uncovered.

Skip the stem when the enclosing file is a crate root (lib.rs, main.rs)
or directory module (mod.rs); those are transparent in Rust's module
tree. ignore_nested_modules already had the lib/mod guard but visit_mod
did not; main.rs was missing from both.
