Bundling the two widenings: four call sites pass `&stream.avail_in` directly to `use_pack()`, and widening either type fencepost alone would force a bridge variable at each. Doing both together is the simpler end state and is the prerequisite for the `do_compress()` widening in the next commit, which is what lets `write_no_reuse_object()` lose its last `cast_size_t_to_ulong()` shim. The unsigned-long locals widened at the other `use_pack()` callers (avail / remaining / left) hold pack-window sizes bounded by `core.packedGitWindowSize`, so the change is type consistency rather than a new >4GB capability. `git_zstream.avail_in`/`avail_out` likewise reach zlib's `uInt` fields only after `zlib_buf_cap()`'s 1 GiB cap, so the wrapper already accepted `size_t`-shaped inputs in practice.
