Initial release: business-name finder with live domain availability

Free, no-account tool for naming a business and finding a domain you can
actually register.

Availability uses no paid API and no key. IANA's RDAP bootstrap maps ~1,200
TLDs to their authoritative registry servers (404 = free, 200 = taken); the
handful with no RDAP at all (.io, .co, .me, .sh, .gg, .us) fall back to a DNS
NS lookup and are reported as "probably free" rather than confirmed, because a
registered-but-undelegated domain is indistinguishable that way.

Name generation is pure, deterministic, and client-side — eight strategies over
a curated word bank, ranked by a scorer that does the real quality work. Three
of its guards (prefix-only hint matching, -er-only syncopation, truncation
rejection) exist because of specific bad output and should not be relaxed.

Optional AI suggestions use the visitor's OWN Anthropic/Gemini key from
localStorage, called browser-direct, so this stays free to run.
