Packfile generation on top of the git core reader: walk the object
graph from a set of wanted refs and serialize a version 2 packfile.
Objects are stored undeltified (each entry is just the zlib-compressed raw object), so generated packs are larger than git's own but valid for any client. The pack is assembled in memory — peak use is roughly the compressed pack size.

collect_objects(
git_dir,wants) ->objects,err
Collect all objects reachable from the given commit/tag SHAs
Walks commits (parents + trees), trees (entries, skipping gitlinks),
and annotated tags. Returns an array of { sha = hex, type = str }.
build_pack(
git_dir,objects) ->pack,err
Build a version 2 packfile containing the given objects, undeltified
