feat: implement core application structure with Fastify server and SQLite persistence

- Add Fastify server in `app/src/index.ts` with health check and API routes for game state and turn processing.
- Create `latentEntities.ts` to handle personal item plausibility and promote beliefs to facts based on actor context.
- Introduce `llmAdapter.ts` for action extraction from prose input.
- Develop `truthEngine.ts` for pure validation logic, handling all verbs with explicit rejection reasons.
- Define new types in `types.ts` for facts, affordances, and latent entity requests/resolutions.
- Update `docker-compose.yml` for improved service structure and volume management.
- Create frontend structure with React, including Dockerfile, Vite configuration, and initial components for state inspection.
- Implement basic styles and HTML structure for the frontend application.
- Document current status and next steps in `thoughts.md`.
