* The DWIM logic in 'git worktree add' sometimes tried to infer a
remote-tracking branch when an explicit '-b' or '-B' option was
given to create a new branch, causing the explicit branch name to
be ignored, which has been corrected.

* The command line completion (in contrib/) has been taught to handle
the experimental 'git history' command.

* The object database (odb) API has been refactored to distinguish
between missing objects and corrupt ones by returning more
descriptive error statuses. Both the packed and loose backends now
faithfully propagate error details using a generic strbuf error
mechanism, removing backend-specific leakage from central lookup
paths.

* The object database layer has been simplified by eagerly loading
alternate object directories upon initialization, instead of
deferring it to the first object lookup. This eliminates the need
for scattered lazy-loading calls throughout the codebase and paves
the way for integrating alternates with the pluggable backends.

* The threshold for geometric repacking to trigger based on loose
object count has been adjusted to match that of 'git gc --auto',
preventing over-aggressive repacking during concurrent writes.

* The 'git receive-pack' command has been updated to use a new ODB
transaction interface for writing incoming packfiles, making it more
backend-agnostic.

* The mechanism to generate a packfile corresponding to the result of
a fetch/push has been made pluggable through a set of object
database callback functions, removing hardcoded references to
'pack-objects' and enabling alternative ODBs to serve packfiles
themselves.

* The pack-objects command has been updated to record the total bytes
written to pack files in trace2 output, allowing performance
analysis of different compression settings by comparing the
resulting pack sizes.

* The trailer parsing machinery has been updated to avoid mistaking
