Razvan Dimescu 7047767dc2 feat: per-suffix conditional forwarding rules (#82) (#84) ...

* feat: per-suffix conditional forwarding rules in numa.toml (#82)

Adds a `[[forwarding]]` config section so users can explicitly route
domain suffixes to specific upstreams. Config-declared rules take
precedence over auto-discovered rules (macOS scutil, Linux search
domains) via first-match semantics.

Example — the reporter's reverse-DNS case:

  [[forwarding]]
  suffix = "168.192.in-addr.arpa"
  upstream = "100.90.1.63:5361"

Bare IPs default to port 53. IPv6 is supported via
parse_upstream_addr. ForwardingRule::new() constructor replaces
direct struct-literal construction, and make_rule() now delegates
to parse_upstream_addr to fix a latent IPv6 parsing bug.

* feat: accept suffix as string or array in [[forwarding]] rules

Reuses existing string_or_vec deserializer so users can write:
  suffix = ["168.192.in-addr.arpa", "onsite"]
instead of repeating [[forwarding]] blocks per suffix.

* style: rustfmt

* refactor: drop config_count from merge_forwarding_rules return

Log config rules directly from config.forwarding before merging,
keeping the merge API clean of logging concerns.
