* feat(backend): add LLM-powered feed enhancement Add enhancement harness that fills feed item slots and generates synthetic items via OpenRouter. - LLM client with 30s timeout, reusable SDK instance - Prompt builder with mini calendar and week overview - arktype schema validation + JSON Schema for structured output - Pure merge function with clock injection - Defensive fallback in feed endpoint on enhancement failure - Skips LLM call when no unfilled slots or no API key Co-authored-by: Ona <no-reply@ona.com> * refactor: move feed enhancement into UserSession Move enhancement logic from HTTP handler into UserSession so the transport layer has no knowledge of enhancement. UserSession.feed() handles refresh, enhancement, and caching in one place. - UserSession subscribes to engine updates and re-enhances eagerly - Enhancement cache tracks source identity to prevent stale results - UserSessionManager accepts config object with optional enhancer - HTTP handler simplified to just call session.feed() Co-authored-by: Ona <no-reply@ona.com> * test: add schema sync tests for arktype/JSON Schema drift Validates reference payloads against both the arktype schema (parseEnhancementResult) and the OpenRouter JSON Schema structure. Catches field additions/removals or type changes in either schema. Co-authored-by: Ona <no-reply@ona.com> * refactor: rename arktype schemas to match types Co-authored-by: Ona <no-reply@ona.com> --------- Co-authored-by: Ona <no-reply@ona.com>
