[PATCH 0/5] odb: make creation of object database pluggable

Hi,

when creating a new repository we create a couple of on-disk data
structures for the object database. This includes the "objects/"
directory hierarchy with "objects/info" and "objects/pack", which are
specific to the backend.

This patch series makes the creation of the on-disk data structures
pluggable. While we continue to always create "objects/" regardless of
the backend (it's required for a repository to be recognized as such),
the other subdirectories are now created by the backend. This will allow
other backends to plug in their own logic.

The series starts with a small detour into the loose-object map. This
detour is required so that we can defer initialization of the object
database itself to a later point in time.

The series is based on 9a0c4701dc (The 7th batch, 2026-07-22).

Thanks!

Patrick
