770574f575 Flatten proxy config to a bool (drop the caddy key)
CaddySpec had only `enable` left (path_prefix/host removed; extra_snippets was
unused), so `proxy: { caddy: {} }` was three levels of nesting for a checkbox —
and it invited drift (supabase silently reverted to proxy.caddy.host). Replace it
with a plain `ServiceSpec.proxy: bool`.

- Model: remove ProxySpec/CaddySpec; `proxy: bool = False`. Readers simplified to
  `bool(svc.proxy)` (generator, castle-api summaries, CLI info).
- CLI create / dashboard editor + create form: write `proxy: true` / a checkbox.
- Configs migrated to `proxy: true` (and supabase's stale proxy.caddy.host block
  removed).
- Docs (registry, dns-and-tls, design, stack guides) + tests/fixtures updated;
  also fixed lingering path-model staleness in the stack guides.

43ef1cc588 Subdomain-only gateway routing; drop path prefixes
Collapse the two proxy shapes (path_prefix + host) to a single checkbox: a
service is either port-only, or exposed at <service-name>.<gateway.domain>. Path
routes and their prefix-stripping foot-guns are gone; the subdomain is always the
service name (rename the service to change it).

- Schema: CaddySpec is just `enable` (presence = expose). service_proxy_targets
  returns (expose, port, base_url); Deployment carries `subdomain` (was
  proxy_path/proxy_host). Registry/deploy/mesh/CLI updated in lockstep.
- Generator: compute_routes emits one host route per exposed service/frontend
  (address = name). acme mode = one *.<domain> site with a reverse_proxy matcher
  per service + a file_server matcher per frontend; the :<port> site redirects to
  the dashboard. off mode = a HTTP control plane on :<port> (dashboard at / +
  /api → castle-api); other services are port-only.
- Dashboard/API: castle-app and castle-api are ordinary subdomains. The dashboard
  derives the API base at runtime (castle-api.<domain> on a subdomain, else /api)
  and calls it cross-origin — castle-api already allows CORS *. Frontends build
  with VITE_BASE=/ (served at their subdomain root).
- CLI: `service create` drops --path/--host; --no-proxy makes it port-only.
- Docs/tests reworked for the model; docs use generic placeholders only (no
  personal host/domain/IP details).

a022a136fe Retire gateway.tls=internal; host routes use a bare subdomain label
acme mode fully replaced the internal-CA path (which required installing a private
CA on every device — the exact pain, esp. on Android, that acme avoids). Remove
`internal` entirely and simplify how services declare host routes.

- Generator (caddyfile.py): drop the `tls internal` branch — modes are now
  `off` | `acme`. In acme mode the published subdomain is the **first DNS label**
  of `proxy.caddy.host` (a bare `claw`, or a legacy `claw.civil.lan`, both →
  `claw.<domain>`), so services stay domain-agnostic and the declared value is
  authoritative again (no more silent service-name override). Shared
  `_host_matcher_block` reused by off-mode and the acme wildcard site.
- castle-api: delete `GET /gateway/ca.crt`, `_gateway_ca_pem`, `_ca_fingerprint`
  and the now-unused imports; drop `ca_fingerprint` from `GatewayInfo` (keep
  `tls`).
- Dashboard: remove the CA-cert download button + unused imports; drop
  `ca_fingerprint` from the `GatewayInfo` type.
- Tests: replace TestCaddyfileTlsInternal with an off-mode class (keeps the
  runner-agnostic host-route coverage); acme tests assert first-label derivation
  incl. label-wins-over-service-name; drop the castle-api CA-endpoint test.
- Docs: registry.md + dns-and-tls.md — two-mode tables (off|acme), remove the
  internal sections/CA-download, document the bare-label host convention; note a
  domain-less node stays on `off`.

fa3a646064 Add docs/dns-and-tls.md: castle's DNS + TLS approach
A conceptual companion to registry.md's field-level gateway reference. Covers the
two questions (resolve / trust) an internal-only LAN service must answer:

- DNS: gateway-as-ingress, path-prefix vs host routes, LAN name resolution,
  wildcard records, split-horizon (internal names, no public A records), and the
  private-TLD vs public-subdomain zone styles with the worked router/wild-central
  topology.
- TLS: the three gateway.tls modes (off / internal / acme) with when-to-use, the
  internal-CA distribution pain vs the acme DNS-01 "no client setup" win, the
  secure-context (WebCrypto) rationale, the put-a-service-on-HTTPS recipe,
  operational prerequisites (443/80 bind, plugin caddy, DNS token, staging), and a
  decision table.
