fix(cargo-sort): pass manifest directory to cargo-sort, not the bare Cargo.toml

cargo-sort rejects single-Cargo.toml positional args with 'No crate folder
found' when there's no surrounding workspace; it requires a directory. The
wrapper now calls dirname on each manifest and passes the directory, which
works for both root-flat single-crate repos (e.g. alef post-0.18.0) and
workspace subcrates.
