PLUTO-140 DB-perf collector — Pluto app leg (fleet bs-mqg1357zx6m decision): provide Pluto's leg of the evolutiva-dbperf@pluto snapshot+diff collector. (1) dbperfSnapshots table via migration — PARITY with venus's canonical schema (get the DDL + 4-query set from db-venus/pm-venus so all 3 apps match byte-for-byte, like the applog rail); telemetry-table discipline (NO archive-context, short retention prune mirroring appEvents). (2) GRANT the existing applog least-priv reader role SELECT on the snapshot table + the catalog/stat views the 4 queries read (cache / pg_stat_statements top-50 / seq-scans / dead-tuples). (3) hand nw-venus the reader-grant confirmation so it can stand up the systemd timer (daily 04:30 ART → biweekly → monthly). Reversible: drop table + disable timer. Coordinate schema parity with venus BEFORE applying.
