[GSoC][PATCH 0/5] Add refs optimize subcommand

This series introduces `git refs optimize` as a modern replacement for `git pack-refs`, continuing the effort to consolidate commands under the `git refs` namespace.

Meet Soni (5):
  builtin/pack-refs: factor out core logic into a helper
  doc: factor out common option
  builtin/refs: add optimize subcommand
  t0601: refactor tests to be shareable
  t: add test for git refs optimize subcommand
