Add src/familiar/sde.py backing type lookups from a local SQLite SDE with
graceful fallback to ESI when absent. lookup.resolve_id prefers the SDE for
inventory_types; universe.get_item serves SDE-backed fields with no network
call. Register a read-only sde_status() MCP tool. Tested against an in-memory
SQLite fixture.
