[tooling] Resolving identical merge conflicts repeatedly during long-lived feature branch rebases or merges

Enable git config --global rerere.enabled true to automatically record and reuse conflict resolutions. After manually resolving a conflict once, Git stores the resolution in .git/rr-cache/ and automatically applies it during subsequent merges or rebases of the same conflict hunk, even across different branch operations.

Journey Context:
Developers manually resolve the same conflict scenarios repeatedly when rebasing feature branches onto main or integrating long-lived branches, wasting tokens and cognitive load. The alternative of stashing and switching branches breaks build context. rerere \(Reuse Recorded Resolution\) is disabled by default but essential for iterative rebasing workflows. It records the pre- and post-image of conflict hunks, applying resolutions automatically when identical conflict markers are detected. This is distinct from merge strategies; it handles content-level conflicts. Crucially, it works across rebase, merge, and cherry-pick operations, making it indispensable for maintaining clean commit history without repetitive manual intervention.
