Replace the Bash namecheap.sh with a stdlib-only Python CLI (namecheap.py)
that resolves all Copilot PR review feedback:
- Cache the public IP once per run instead of per request
- Build API requests in-process via urllib so the API key never appears
in process argv or shell history
- Broaden multi-part TLD detection (co.uk, com.au, etc.) and document the
limitation
- Allow setup to update existing stored credentials
- Stop soliciting the API key via chat; use terminal getpass or env vars
- Remove non-portable Bash constructs (inline local, grep -oP)
Also normalize domain casing, preserve MX priority 0, accept
case-insensitive record types, and handle mixed-case email-forwarding
attributes. Update SKILL.md and regenerate the skills README.
