Subject: [PATCH] chore: default local dev event store to ClickHouse in
 .env.example

Fresh clones left EVENT_REPOSITORY_DEFAULT_STORE unset, which falls back
to the "postgres" store. The local stack is already ClickHouse-backed
(run replication + CLICKHOUSE_URL), so dev run traces showed up empty
even though the run itself appeared. Default it to clickhouse_v2.
