d789e872b1 feat(kez-chat/web): SW auto-reload on deploy + visible build sha in footer
Two related changes — both aimed at "can you tell what's deployed?"

1. SW auto-update (no more "refresh twice")

   The default vite-plugin-pwa autoUpdate behavior was: new SW
   downloads on first reload, activates on second reload. Users
   refresh after a deploy, still see old bundle, get confused.

   Now:
   • workbox: skipWaiting + clientsClaim → new SW activates and
     takes control of existing pages immediately on install.
   • main.ts listens for `controllerchange` and calls reload() once.
     New SW takes over → page reloads → new bundle loads.

   Net: deploys land on the FIRST refresh after the new bundle is
   reachable. (Caveat: the SW that's currently running has to
   download the new SW first, so the very first refresh after a
   deploy may serve stale + then auto-reload a beat later.)

2. Visible build sha in the footer

   vite.config.ts now runs `git rev-parse --short HEAD` at build
   time and injects __BUILD_SHA__ + __BUILD_TIME__ via Vite's
   `define`. App.svelte's footer renders the sha as a small monospace
   chip linking to the commit on gitea, with the build time on
   hover.

   "kez-chat web v0.1" → "kez-chat  [abc1234]  · source"

   So when you refresh and the chip changes value, you know the new
   build landed. When it doesn't, you know the SW is still serving
   the old bundle.

3. Killed the `apple-mobile-web-app-capable` deprecation warning by
   adding the standard `mobile-web-app-capable` next to it.

6c0f5e2fd5 feat(kez-chat/web): make the SPA installable as a PWA
Now installable on iOS (Safari → Share → Add to Home Screen) and
Android/desktop Chrome (install prompt or Settings → Install app).
Launches in standalone mode with a dark theme color matching the
lock-icon palette.

Stack:
  • vite-plugin-pwa with workbox in generateSW mode, registerType
    'autoUpdate' — new SW activates on next page load, no upgrade prompt
    (chat needs to stay fresh).
  • @vite-pwa/assets-generator for icon variants from a single SVG.
    Source kez-icon.svg = dark squircle (#111827) + amber key glyph,
    drawn inside the 80% maskable safe zone.

Caching:
  • Precaches the SPA shell (~635 KB inc. the zstd WASM, well under
    the 5 MB per-file cap).
  • runtimeCaching 'NetworkOnly' for /v1/* — never cache authenticated
    chat data; every poll must hit the network.
  • navigateFallback to index.html so /messages, /claims, /dashboard
    survive a refresh while offline. The /v1/, /internal/, /.well-known/
    paths are explicitly denylisted from this fallback.

Meta tags (index.html):
  • <link rel="manifest"> + theme-color for Android Chrome.
  • apple-touch-icon-180x180 + apple-mobile-web-app-* meta for iOS,
    including status-bar-style=black-translucent so the dark header
    flows into the notch area in standalone.
  • viewport-fit=cover so safe-area-inset works on notched devices.

Generated artifacts committed under web/public/:
  kez-icon.svg, pwa-{64,192,512}.png, maskable-icon-512x512.png,
  apple-touch-icon-180x180.png, favicon.ico.

Verified live: /manifest.webmanifest serves application/manifest+json,
/sw.js serves text/javascript, all icons return 200.

a9feb1b5b2 feat(kez-chat/web): Svelte SPA — account creation + claims wizard
First real UI for kez-chat. Served by the chat-server as static
files; uses the same HTTP API a native client would (dogfoods the
contract).

Stack: Svelte 5 + TypeScript + Vite + Tailwind 4 + @noble/curves +
@scure/base + canonicalize + idb-keyval + svelte-spa-router.

Bundle: 113 KB JS / 14 KB CSS (gzip: 42 KB / 4 KB).

Pages (all behind hash routing):
  /                 Landing — sign up or restore from seed
  /create           Account creation flow:
                       1. Pick handle, set passphrase
                       2. Show seed for paper backup, require ack
                       3. Confirm
                       4. POST /v1/register, save passphrase-encrypted seed
                          to IndexedDB
  /restore          Stub for restore-from-seed (v0.2: needs
                    GET /v1/by-primary endpoint on the server)
  /unlock           Enter passphrase to derive the AES-GCM key,
                    decrypt the seed, populate session state
  /dashboard       Show handle, primary, registered_at, sigchain URL
  /claims          List locally-cached claims (with publication status)
  /claims/add      Add-a-claim wizard:
                       1. Pick channel (github/dns/web/nostr/bluesky/ap)
                       2. Enter identifier
                       3. SignedClaimEnvelope built + signed in-browser
                          using Ed25519 + JCS, matching the spec exactly
                       4. Show channel-appropriate publish instructions +
                          copyable markdown or JSON artifact
                       5. User marks it published (purely a local note —
                          actual verification is the verifier's job)

Crypto / KEZ helpers (src/lib/kez.ts):
- generateIdentity / identityFromSeed (32-byte Ed25519)
- canonicalBytes (RFC 8785 JCS via the `canonicalize` package — same
  one our Node port uses; produces byte-identical output to Rust)
- signClaim, signRegistration (build envelopes; sign with
  ed25519-sha512-jcs; same alg / key / sig shape as kez-core)
- toPrettyJson, toMarkdown (the same wire encodings the CLI emits)

Key storage (src/lib/identity-store.ts):
- IndexedDB via idb-keyval
- Seed encrypted under user passphrase: PBKDF2-SHA256
  (600,000 iterations, OWASP 2024 guidance) → AES-GCM-256
- Documented limitation: browsers don't have an OS-keychain
  equivalent. Native clients (future CLI/Tauri) will use the OS
  keychain for better protection.

Bundle includes:
- Workaround for TS 5.6+ Uint8Array<ArrayBufferLike> vs ArrayBuffer
  strictness (small asBuffer() helper that copies into a plain
  ArrayBuffer for WebCrypto + Response calls).

Dockerfile updated: now multi-stage with a Node `webbuild` stage
that runs `npm run build` before the Rust binary stage. SPA dist
is copied into the runtime image at /app/web; chat-server's
KEZ_CHAT_WEB_DIR points at it so the SPA is served at /.

What works against the LIVE deployment right now (https://kez.lat):
- Open https://kez.lat → SPA loads (113 KB JS, 14 KB CSS)
- Create account → key gen happens in browser, seed shown for
  backup, encrypted under passphrase, POSTed to /v1/register
- Dashboard → shows registered handle + primary + sigchain URL
- Claims wizard → sign for any of the 6 channels, get publish
  instructions + the right wire format to copy
- Lock / unlock — passphrase-derived AES-GCM, no roundtrips

What's still TODO (v0.2):
- Restore-from-seed: needs GET /v1/by-primary on the server so the
  SPA can discover the handle from a seed
- Actual NATS chat: needs server's auth callout (currently 501) +
  nats.ws client (browser side; package is in deps but not used yet)
- Sigchain integration: append `add` event when user publishes a
  claim, upload to sig-server (needs sig.kez.lat tunnel)
- Verification: in-browser channel fetches (some channels are
  CORS-friendly, others need a server-side proxy)
- Compact (kez:z1:) form: the spec uses zstd, browsers don't have
  native zstd CompressionStream support yet. Workaround in code
  uses deflate-raw with a `kez:zd1:` prefix to make it obvious the
  output isn't spec-compliant; replace with @bokuweb/zstd-wasm or
  similar when we need true compact form in the SPA.
