release: v1.18.0-beta.2 — rootless DNS MTU fix, FrankenPHP log tab

[geodro]

Summary

• Second beta on the 1.18 line. Two fixes, no new features.

Fixed

• Rootless DNS stalled 5–10s per page after dual-stack migration (fix(network): pin bridge MTU to 1500 and respawn aardvark-dns on network recreate #242). Two separate Fedora rootless podman quirks, both triggered by the IPv6 migration in beta.1. First, the lerd bridge came up with a 65520 MTU and glibc's resolver hit EMSGSIZE on UDP, falling back to TCP and eating 5+ seconds per lookup; EnsureNetwork and MigrateNetworkToIPv6 now pin --opt mtu=1500. Second, RemoveNetwork only unlinked aardvark-dns's config file, so the running daemon held the stale inode and returned NXDOMAIN for containers that joined the recreated network; RemoveNetwork now also runs pkill -f aardvark-dns so podman respawns it against the fresh config on the next container join.
• FrankenPHP sites rendered a "PHP-FPM" log tab pointing at the wrong container (fix(ui): label FrankenPHP log tab and stream from the right container #243). The Web UI and TUI both labelled the runtime log tab as "PHP-FPM" and pointed its SSE stream at lerd-php*-fpm, which does not exist for per-site FrankenPHP deployments. The tab now reads "FrankenPHP" and streams from lerd-fp-<site>, and enrichFPM checks the frankenphp container so fpm_running is accurate for those sites.
