/**
 * Optional single-tenant ClickHouse store (ADR 0020): the scale path for
 * self-hosters who outgrow DuckDB's single read-write process. It carries the
 * **full** analytics surface — no stubbed aggregates — by rendering the same
 * dialect-agnostic builders with {@link clickhouseDialect} and executing them
 * over a ClickHouse server. Events live in the wide `events` table (plus the
 * dedicated `node_samples`); metadata (projects, API keys, scene registry) is
 * re-homed into the same database.
 *
 * The schema is migrated on creation (migrations are idempotent and forward-only),
 * so the store is usable out of the box once a ClickHouse server is reachable.
 * Connection settings come from `readDbSettings().clickhouse` (the `CLICKHOUSE_*`
 * env vars).
