v0.15.5

Bug Fixes

• Multi-segment custom TLDs: --tld and PORTLESS_TLD now accept dotted DNS names such as dev.example.com, so local URLs can mirror production structure. validateTld checks per-label DNS rules and the 253-character total limit, overlapping TLDs resolve by longest match, and cert cache filenames stay under the filesystem name limit for long hostnames. (#365)
• WebSocket over HTTP/2: Proxy now advertises RFC 8441 extended CONNECT and bridges :protocol websocket streams to an HTTP/1.1 upgrade against the backend, fixing dev server HMR for browsers that negotiate h2 over ALPN. Plain-HTTP upgrades on the TLS port are proxied instead of dropped, and a backend that rejects the handshake or answers with a bad Sec-WebSocket-Accept now gets a 502 instead of a silently destroyed socket. (#363)
