bvandeusenandClaude Opus 5.5 656e127fd8 perf(metrics): a day of one metric reads from the index alone, built after boot (#5490) ...

#5490 "A day of one metric reads fast even cold". A cold 24 h series read
measured 18.3 s against 63 ms warm (#5485): every sample's row sat on its own
heap page. ix_plugin_metrics_series_value carries `value` (INCLUDE), so the
read is an index-only scan; it replaces the plain series index from 0023.

It is built once, with CREATE INDEX CONCURRENTLY from a task started after the
app is serving, never in a migration, so the boot isn't held while it builds
over the live table (#5220) and ingest and pages carry on. A build cut short
by a restart leaves an INVALID index; the next boot drops and rebuilds it.
Later boots find it present and only check. Postgres keeps it current on each
insert, as it did the index it replaces.
