Build Verse: a poem-quote app on the agent-native chat template

Adds a Postgres-backed quotes domain (poems/quotes/favorites) exposed as
five agent-native actions (list-quotes, get-random-quote, create-quote,
toggle-favorite, list-favorites) callable from both chat and the React UI
via useActionQuery/useActionMutation. Moves the primary UI from chat to a
mobile-first Quotes/Favorites experience (chat moves to /chat), adds
manual OpenTelemetry instrumentation exporting traces/metrics/logs over
OTLP, and wires a local Docker Postgres for shared state.
