feat: default port 443 for domain remotes, strip from display (v0.9.4)

- Domain-like --remote endpoints default to port 443; :443 is optional
- _normalize_endpoint strips :443 before storage in remotes.json
- _load_remotes normalises keys on load (backward compat migration)
- _remote_display_name omits :443 for domain endpoints
- _resolve_connect_endpoint adds :443 back for TCP connection
