usage 7.0.1 ډاونلوډ

This release reduces how much code usage-argv adds to CLIs that embed it. Help, -h, version, completion and parse-error output stay byte-for-byte the same, and startup and parse speed are unchanged.
Changed
- (lib) Help, completion and error rendering in usage-argv produce less machine code (#1551, #1553, #1554, @jdx). String appends, text wrapping, slicing, searching, completion splitting and error suggestions now go through shared helpers instead of being expanded at every call site. In stripped release builds of oxlint and oxfmt, the three PRs together removed about 85 KB from each binary. That covers most of the size those CLIs gained when they moved from bpaf to usage-rs.

Fixed
- (complete) Split::walked and Split::argv no longer panic when cword is out of range. They now return the whole word list and an empty slice (#1554, @jdx).
