Rewrites the compiler from ~440 to ~1700 lines covering all major shorewall firewall features: loopback, conntrack fast-path, anti-spoof, DHCP, intra-zone, blacklist/whitelist, conntrack notrack, tunnels (13 types), rules with sections, DNAT/redirect, SNAT/masquerade, static NAT, policies with zone exclusions, MSS clamping, rate limiting, connection limiting, negated addresses, ICMP type matching, TCP RST reject, user/UID matching, mark match/set, NFQUEUE, NONAT, and policy-level rate/conn limiting. Adds full config types for all shorewall subsystems (mangle, accounting, maclist, netmap, providers, tunnels, conntrack, blrules, proxyarp/ndp, routes, tc, secmarks), shorewall migration tooling, expanded CLI commands, expression-level diff engine, and 49 unit tests.
