v1.5.0 — HTTP/3 server information panel

Added

• HTTP/3 server information panel on the /http3 page: HTTP version used, status code, server IP/port, DNS / connect / TLS / TTFB / total response timings, and the full list of response headers returned by the origin.
• Server info is emitted as a new server_info SSE event during the check. When curl has QUIC support, the panel prefers data observed over HTTP/3; otherwise it falls back to the HTTP/2 or HTTP/1.1 probe.

Notes

• For richer HTTP/3-specific metadata (connection ID, per-packet stats, etc.) the host server needs a curl build linked against ngtcp2 + nghttp3 or quiche. Without it, the panel still reports the server's actual HTTP version and headers, but the numbers come from the HTTP/2/1.1 probe.
