Emit instance_uuid from pg_stat_ch.extra_attributes through the shared definitions for native ClickHouse, OTLP logs, and unified Arrow; also support legacy Arrow. Add the events_raw column and extend existing tests. Missing UUIDs remain empty.

Apply the table migration before upgrading native exporters. Arrow ingestion tolerates the extra field before the column exists. Provisioning and downstream CMC columns/MV projections need separate updates; the current bridge keeps converting UBIDs. Rollback retains the additive column for dependent views.

Validation: local PostgreSQL 18 build; all four formats passed missing/configured/reloaded UUID checks; 10 regression and 3 isolation tests passed. CI is green. Native checks used LZ4: ClickHouse 26.9's ZSTD default exposes an existing decoder failure also reproduced on main. OTLP/Arrow passed with ZSTD.
