Defame1297 0fde892f20 refactor(git-branches): retrofit to the ADR-0020 context contract
Description 612 -> 273 chars, body 1124 -> 457 words. Branch patterns,
operations, merging, comparison, and the orchestrator contract move to
references/.

Corrects rebase routing in four places: this skill sent rebase to
git-history, which carries no rebase content and disclaims it. Rebase is
git-commits'; cherry-pick and revert stay git-history's. Drops a Step 3
gate on a rebase flow this skill does not have.

Comparing two branches

The two-dot and three-dot forms mean different things and are easy to swap by accident — check the direction before reporting a result.

  • git log main..feature — commits on feature that are not on main.
  • git log feature..main — the reverse direction: commits on main not on feature.
  • git log --left-right main...feature — both diverging sets at once (symmetric difference).
  • git diff main...feature — the diff from the common ancestor to feature's tip, which is what a reviewer sees, rather than the diff between the two tips.
  • git merge-base main feature — print the common ancestor commit.
