Kez/kez-chat/deploy/Dockerfile.sig-server
Tudisco 111b23b94b feat(kez-chat): scaffold the home server (v0.1)
First runnable kez-chat-server binary plus its docker-compose deploy
recipe. Implements steps 2-3 of the document.md sequenced plan; the
rust-lib refactor (step 1) is deferred — chat-server path-deps on
rust/crates/kez-core for now, which works and matches what
rust-sig-server already does.

What's in this commit:

kez-core (1-line change)
- New public `verify_envelope<T>(payload, signature)` helper that
  dispatches Schnorr / Ed25519 / future suites by signature.alg.
  Used by chat-server's registration verifier; downstream value
  beyond chat-server too.

kez-chat-server (new crate)
- src/main.rs: tokio + axum + tracing entry; clap config; graceful
  Ctrl-C shutdown.
- src/lib.rs: re-exports so tests can drive the same router.
- src/config.rs: env/flag config (bind, db, server, sig_server_url,
  web_dir) with defaults sane for both dev and prod.
- src/error.rs: typed ApiError → structured JSON responses with
  stable error codes.
- src/store.rs: SQLite-backed handle registry, UNIQUE on both
  (handle) and (primary_id); race-safe via SQL primary key.
- src/handles.rs: username validation (length, charset, reserved
  list, must start with letter/digit).
- src/registration.rs: SignedRegistration envelope sharing KEZ's
  JCS canonical-bytes pattern; signature verification via the new
  kez-core helper; replay protection via ±5-minute clock skew check.
- src/api.rs: all six routes in one file —
    GET  /v1/healthz
    GET  /v1/u/:handle
    POST /v1/register
    GET  /.well-known/webfinger
    POST /internal/nats/auth   (501 stub for v0.1; wired up in v0.2)
    GET  /                     (placeholder HTML; ServeDir when web/dist exists)

tests/http.rs — 13 integration tests
- Stands up the real router on a random port; uses reqwest.
- Coverage: healthz, lookup-404, full register→lookup round-trip,
  duplicate-handle conflict, wrong-server rejection, reserved-name
  rejection, tampered-signature rejection, stale-timestamp rejection,
  WebFinger success + wrong-server-404, placeholder SPA renders,
  NATS callout 501, JCS determinism sanity.

deploy/
- Dockerfile: multi-stage build (rust:1.86-slim → debian:bookworm-slim).
  Build context is repo root so the path dep on kez-core resolves.
  Runtime image ~50 MB; runs as non-root uid 10001.
- Dockerfile.sig-server: same pattern for the existing
  rust-sig-server, so the stack builds from one git pull.
- docker-compose.yml: three services (chat-server + nats + sig-server)
  with named volumes for persistence. Ports: 6969 (chat HTTP),
  4222/8443/8222 (NATS native/ws/monitoring), 7878 (sig-server).
- nats.conf: WebSocket on 8443 for the browser SPA, JetStream
  enabled, auth_callout pointing at chat-server's
  /internal/nats/auth endpoint (issuer nkey is a placeholder — must
  be replaced with a real one before going live).

README.md
- Documents all endpoints with example bodies.
- Quick-start for both local dev and full Docker compose.
- Honest list of what's in v0.1 vs what's still stubbed.

Smoke-tested running on 127.0.0.1:6969:
  GET /v1/healthz       → {"server":"kez.lat","status":"ok","version":"0.1.0"}
  GET /                 → placeholder HTML rendering
  GET /v1/u/ghost       → 404
  POST /internal/nats/auth → 501 with "wired up in v0.2"

cargo test  → 13 passed.
cargo build --release → 19.6s, clean.
