James Coleman 5095d90fa4 Advertise capability flags and harden backend semantics
- New Capabilities: PortPair, Negation, RejectAction,
  FamilyWithoutAddress, DenyActionFromConfig, advertised per backend.
- coversDirection isolates DirForward even when output is unowned;
  add splitNATDualRow so a concrete-family removal re-adds the opposite
  family's NAT translation.
- Resolve ip6tables/ufw ICMPv6 type aliases; ParseNATKind rejects the
  "invalid" sentinel as input while JSON round-trips it.
- Sync counts additions on mid-batch failure and uses RuleBatcher.
- NewManager runs a probe loop joining each backend's reason for
  diagnosability; services.go drops "generated" from enabled, handles it
  on enable, clears start-limit-hit on restart, and matches rc.local by
  token.
- nftables: per-source connection limits (meter set), quoted-token
  parsing preserving log-prefix spacing, digit-led prefix sanitizing.
- apf/csf: deny-action-from-config with cached STOP settings, port lists
  and inexpressible shapes routed through the pre-hook, confKeyApplies
  guard against a missing config line.
- atomic config writes fsync before rename and resolve symlinks;
  readConfValue is last-assignment-wins; runCommand preserves the exit
  code through the wrapped error.
- Move coreos/go-systemd to the maintained v22 module directly.
