test(fix[docs]): Drop the unreachable AGENTS.md skip

why: iter_documentation_markdown_files walks README.md and docs/**,
and this branch removes docs/AGENTS.md and docs/CLAUDE.md, so the
name guard can no longer match anything. Code nothing can reach is
the kind this project's own writing guide says to delete.

what:
- Remove the AGENTS.md/CLAUDE.md skip from the documentation walk
