andreasandClaude Sonnet 5.5 885d5dc937 feat(client): re-resolve the server hostnames at the DNS TTL
hbc, hbc_mini.py and hbc_mini.c resolved the server once at startup, so an
address change needed a client restart. They now re-resolve every TTL seconds
(smallest A/AAAA TTL, floor 30s, 300s when unknown) and re-point, add or drop
connections to follow the new addresses; a failed lookup keeps the current ones.
