Andreas Wrede 588eb2a792 feat: retry DNS resolution indefinitely and add -4/-6 flags in hbc and hbc_mini.c 
Mirror the same changes from hbc_mini.py: retry host resolution with
exponential backoff (5s→60s) instead of exiting on DNS failure, and add
mutually exclusive -4 / -6 flags to restrict connections to IPv4 or IPv6.

In hbc (main.py) the retry sleep is interruptible via the shutdown_event.
In hbc_mini.c signal handlers are moved before the resolution loop so
SIGINT/SIGTERM can break the retry during startup.

andreas 2df2ad18c9 scripts/c: add single-file C port of hbc_mini 
hbc_mini.c is a full port of scripts/hbc_mini.py requiring only zlib,
pthreads, and a C11 compiler. Supports Linux, FreeBSD, NetBSD, and
DragonFly BSD with platform-specific plugin backends:

  - cpu_monitor:    /proc/stat (Linux) or kern.cp_time sysctl (BSD)
  - memory_monitor: /proc/meminfo (Linux), vm.stats.vm.* (FreeBSD),
                    struct uvmexp (NetBSD)
  - network_monitor:/proc/net/dev (Linux) or getifaddrs()+if_data (BSD)
  - disk_monitor:   df -P (all platforms)
  - ping_monitor:   ping subprocess (all platforms)
  - nagios_runner:  shell commands with perfdata parsing (all platforms)
  - os_info:        uname() + /etc/os-release (Linux) or kern.osrelease (BSD)

Build: cc -O2 -o hbc_mini hbc_mini.c -lz -lpthread -lm
