/**
 * OSS default store (ADR 0020): a single persisted DuckDB file holding both
 * events and metadata, with the **full** analytics surface — no stubbed
 * aggregates. In-process and zero-service, so a self-hosted collector needs no
 * external database. Every aggregation is the dialect-agnostic builder rendered
 * with {@link duckdbDialect}; metadata (projects, API keys, scene registry) is
 * re-homed into the same file.
 *
 * The schema is migrated on creation (migrations are idempotent), so the store
 * is usable out of the box. Pass `":memory:"` for an ephemeral store (tests).
