Update binary name, DB path, session cookie, deploy scripts, systemd
service, Docker config, CI workflow, and .dockerignore. Remove stale
Claude command and settings files.
Add GetPlayerID, GetUserID, GetNickname to the sessions package.
Remove the inline player-ID-from-session pattern duplicated across
every handler in c4game and snakegame, and the local getPlayerID
helper in snakegame.
Replace CDN-hosted datastar beta.11 with local v1.0.0-RC.7 to fix
client-side expression incompatibilities with the Go SDK. Also fix
quoted CSS class keys in data-class expressions, harden session cookie
settings (named cookie, Secure flag), simplify SetupRoutes to not
return an error, and regenerate templ output.
Migrate from the via meta-framework to direct dependencies:
- chi for routing, templ for HTML templates, datastar for SSE/reactivity
- Feature-sliced architecture (features/{auth,lobby,c4game,snakegame}/)
- Shared layouts and components (features/common/)
- Handler factory pattern (HandleX(deps) http.HandlerFunc)
- Embedded NATS server (nats/), SCS sessions (sessions/), chi router wiring (router/)
- Move ChatMessage domain type from ui package to game package
- Remove old ui/ package (gomponents-based via/h views)
- Remove via dependency from go.mod entirely
