[PATCH 00/10] odb: make consistency checks pluggable

Hi,

this patch series makes object database consistency checks pluggable.

This series is built on top of 2c3adbb2c4 (The 18th batch, 2026-08-24) with the following two dependencsie merged into it:

  - ps/odb-eagerly-load-alternates at 0076dc9f81 (odb: drop
    `alternates_db` field, 2026-08-17)

  - ps/odb-pluggable-pack-generation at 5176dd3d05 (bundle: generate
    packfiles via the object database, 2026-08-21)

Thanks!

Patrick
