Commit Message

  Schema priming, guide injection, and conversation history persistence

  Inject catalog schema, MCP guide prompts, and ERMrest syntax documentation
  into the system prompt on the first turn of default-catalog conversations.
  Priming uses get_catalog_info + get_schema (skipping the "public" system
  schema) instead of rag_search, which returned fragmentary JSON blobs that
  were less useful as LLM context. Primed content is cached on the session
  and reused on subsequent turns without re-fetching.

  Add open_session() to mcp_client for batching multiple MCP calls on a
  single connection, eliminating per-call ListToolsRequest overhead during
  priming. Add get_prompt() for fetching MCP prompt resources.

  Persist conversation history across session expiry via a long-lived
  history:{user_id} store key (default 7-day TTL). Both authenticated and
  anonymous sessions restore history on re-authentication. Add GET /history
  and DELETE /history endpoints; the browser loads prior conversation on
  page load and offers a clear-history button.

  Harden the system prompt with five MANDATORY RULES (schema context usage,
  multi-table join guidance, zero-result acceptance, full-column display,
  operational rules) that work reliably with both Haiku and Sonnet. Raise
  _TOOL_RESULT_TO_CLAUDE from 6000 to 10000 chars. Add status SSE event
  type for priming progress indicators.

  Default model: claude-haiku-4-5-latest (sufficient after prompt hardening).
