Eliminate all code paths, configuration, and documentation related to running
without authentication. Require AUTH_SECRET and BASE_URL at startup, updating
middleware, server logic, and runtime checks to assume auth is always enabled.
Simplify onboarding, settings, and test helpers to reflect mandatory auth.
Update environment examples, Docker and deployment docs, and CI/test configs.
Remove no-auth-specific UI flows, test cases, and feature toggles.
Expand and clarify documentation for TTS segment storage, including key layout, cleanup, and CLI access in object storage. Add details on the `tts_segments` schema and migration process. Revise local development and Docker quick start guides with improved prerequisites, platform-specific setup instructions, and updated TTS provider references. Document new usage of `AUTH_SECRET` for TTS segment text fingerprinting.
Implement AbortController in ConfigContext, PDFContext, and preference sync to prevent race conditions during session changes or rapid navigation. Refactor document preview routes into shared utilities and add LRU caching for text previews to optimize memory. Update documentation for Better Auth schema ownership and migration workflows. Fix issues with Postgres system user seeding and better-sqlite3 configuration.
