[tooling] Repeatedly resolving identical merge conflicts during long-running feature branch rebases

Enable git rerere \(Reuse Recorded Resolution\) globally: \`git config --global rerere.enabled true\`. Once enabled, Git automatically records conflict resolutions and reapplies them when encountering the same conflict hunk, persisting across rebase, merge, and cherry-pick operations.

Journey Context:
Most developers resolve the same conflict dozens of times when iterating on long-lived branches. Without rerere, you must re-resolve identical conflicts after every upstream rebase or when cherry-picking between branches. Rerere stores the resolution context in .git/rr-cache \(which can be committed and shared via bundle if needed\). The tradeoff is slightly more disk usage, but the time savings on complex rebases is massive. Critically, rerere only triggers on identical conflict hunks, so it's safe to enable globally without side effects.
