docs: refine repository guidance

[qeude]

Keep repository guidance focused on durable conventions.

[greptile-apps]

Greptile Summary

Removes the temporary restriction against naming or linking external macOS window-manager implementations while retaining the repository-wide English-language requirement.

• Deletes the one-off external-product naming rule from AGENTS.md.
• Preserves the adjacent guidance to respect user changes and avoid reverting unrelated work.

Confidence Score: 5/5

The documentation-only change appears safe to merge.

The removed instruction exactly matches the PR’s stated intent, and the remaining English-language and change-preservation rules remain intact.
