Stage 17 round 6 (#16-20): landing page, /app/ move, cache + stream fixes
Close out Stage 17 round 6:

- Landing page at / — one Vite build with two entries (index.html = game
  SPA, landing.html = a lightweight landing reusing the theme/i18n/
  aboutContent leaf modules, not the app store).
- Move the web game SPA to /app/; the Telegram Mini App stays at /telegram/
  (gateway webui.Handler(stripPrefix, indexName): landing at /, SPA at /app/
  + /telegram/). Per-language "Play in Telegram" link via new
  VITE_TELEGRAM_LINK_EN/_RU build vars (button hides when unset).
- Cache headers: hash-named /assets/* immutable, HTML shells no-cache (the
  go:embed zero modtime emitted no validators, so the client re-downloaded
  the whole bundle every launch).
- Live-stream 15s abort fix: an immediate heartbeat on open + a 10s default
  interval (the first tick at 15s raced the edge idle timeout -> reconnect
  storm).

PLAN/ARCHITECTURE(§13)/FUNCTIONAL(+ru)/gateway+ui+deploy READMEs updated;
round 6 closed. Tests: gateway webui/connectsrv units, ui landing unit + e2e,
full e2e (60) green.

# Multi-stage build for the gateway service. A node stage builds the static UI
# (Vite), the result is embedded into the Go binary (gateway/internal/webui/dist),
# and the Go stage — mirroring platform/telegram/Dockerfile — yields a static
# binary shipped on distroless nonroot. So the single binary serves the SPA at /
# and /telegram/ (docs/ARCHITECTURE.md §13) with no separate static container.
#
# The production UI build vars are image build-args, baked into the bundle.
# Build from the repository root so go.work, pkg/, gateway/ and ui/ are all in the
# Docker context:
# docker build -f gateway/Dockerfile \
# --build-arg VITE_GATEWAY_URL=https://example \
# -t scrabble-gateway .
