Note

Low Risk
Documentation-only updates with no runtime or deployment logic changes.

Overview
Documents mint add-domain <domain> so users can register a custom domain from the terminal (after mint login), using the configured or first account subdomain, waiting up to 10 seconds for DNS values, then printing TXT / CNAME setup guidance with a dashboard fallback for pending records.

Adds a full mint add-domain section to the CLI command reference and a Tip on the custom domain guide linking to that command, in English, Spanish, French, and Chinese.

Locale files outside PR scope

Low Severity

This PR’s description scopes localization to English and Spanish, but the diff also changes French and Chinese pages. .mintlify/AGENTS.md says docs PRs should only edit English and leave es/, fr/, and zh/ to the translation workflow, so these locale edits look out of scope and risk conflicting with that process.
