Build MVP: launcher, constructor, and AI game generation

A self-hosted, Roblox-flavored game platform: browse/play published
browser games, build them by hand or by describing them to an LLM.
Fully independent from top-tickets — separate repo, DB, port (8082).

- Auth: email+password accounts (argon2, httpOnly session cookies),
  no admin/agent split — every account can create and play.
- Three game templates (quiz, clicker, maze), each a zod schema paired
  with a Phaser 4 Scene that renders purely from a validated instance
  of that schema — manual and AI-generated games hit the same
  renderer, so a saved game is always guaranteed to load and run. The
  maze schema BFS-validates that the exit is reachable from the start.
- Manual constructor: per-template builder forms, draft/publish/edit/
  delete, a launcher grid of published games, a full-bleed play page.
- AI generation: Anthropic API key configured under Settings → AI
  (encrypted at rest, validated with a live call before saving, same
  shape as top-tickets' mailbox/LDAP settings). Generation uses the
  SDK's zodOutputFormat/messages.parse to force schema-shaped JSON
  output, with one retry feeding back the validation error. Output
  always prefills the manual builder for review — never auto-published
  blind. Clean, distinct error message when no key is configured yet
  (no silent fallback exists here, so it doesn't pretend one does).
- Docker Compose on port 8082 (bakes in the busy_timeout=30000 SQLite
  pragma from day one — top-tickets hit this build-time race twice).

Deferred: more templates/genres, drag-and-drop level editor, likes/
leaderboards, AI-generated sprite assets, multiplayer, moderation.
