Viktor Barzin 0dd4a31eff docs(immich): cap server-side job concurrency to protect sdc + log recurrence
A library-wide Duplicate Detection run on 2026-06-01 fanned the ML/thumbnail
backfill out at thumbnailGeneration concurrency 8, saturating the shared sdc
HDD and starving etcd -> kube-apiserver down ~30 min (5th IO-pressure incident
on sdc). Capped server-side thumbnailGeneration/metadataExtraction/library to 2
in the Immich DB system-config; documented in the Immich row and recorded the
recurrence + still-TODO IO-isolation fixes in the 2026-05-25 post-mortem (this
also commits that previously-untracked post-mortem).
