perf: skip build_push_objects entirely on bundle push path

build_push_objects read all 5162 object blobs (129 MB) to compute n_objects for the routing decision — then on the bundle path its result was thrown away.

Routing now uses len(commit_walk['all_object_ids']) which is free (already computed by walk_commits). build_push_objects only runs on the stream path where its result is actually used.

Eliminates ~4s of dead object loading on every large push.
