It caches the last known-good config and, when the control plane is unreachable, keeps applying that cache — it never fails closed. - internal/agent: rendered-config types, HTTP client (fetch + status report), on-disk cache, on-device DNS resolver for dns sets (honors the device's configured resolver, fail-safe on lookup failure), and the pull-apply-report loop behind a mockable Applier. - Translate the interface-agnostic, address-matched rendered model into native tomswall config using the "all:<cidr>" any-interface source/dest form, reusing the existing differential engine.

Add tomswall agent (control-plane pull mode)

Add `tomswall agent`: it pulls this device's compiled config from tomswallapi,
differentially applies it, and reports the applied generation. It caches the
last known-good config and, when the control plane is unreachable, keeps
applying that cache — it never fails closed.

- internal/agent: rendered-config types, HTTP client (fetch + status report),
  on-disk cache, on-device DNS resolver for dns sets (honors the device's
  configured resolver, fail-safe on lookup failure), and the pull-apply-report
  loop behind a mockable Applier.
- Translate the interface-agnostic, address-matched rendered model into native
  tomswall config using the "all:<cidr>" any-interface source/dest form, reusing
  the existing differential engine. Named-set members are inlined as concrete
  addresses (native nft set references are a tracked follow-up).
- cmd/tomswall: wire the `agent` subcommand (flags + TOMSWALL_* env, --once).
- Unit tests: translation, cache, and the don't-fail-closed fallback loop.
- Add DESIGN.md documenting the control-plane architecture.

Add comprehensive nftables compiler with shorewall feature parity

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.

Initial scaffold for tomswall

Spiritual successor to shorewall — manages nftables directly via
google/nftables. Reads a single YAML config covering zones, interfaces,
hosts, policy, rules, snat, and named portgroups. Computes differential
changes against the running nftables state and applies them atomically.
Supports detecting and purging rules added outside of tomswall.
