[tooling] Re-resolving the same merge conflicts repeatedly during long-lived feature branch rebases

Enable \`git config --global rerere.enabled true\` to automatically record and reuse conflict resolutions, applying them automatically on identical hunks.

Journey Context:
Agents working on long-running branches often rebase against main multiple times, hitting the same merge conflicts in the same files repeatedly. Without \`rerere\`, they manually resolve the same diff hunks every time. \`rerere\` \(Reuse Recorded Resolution, since Git 1.5\) automatically records the resolution of a conflict when it is resolved. On subsequent identical conflicts \(same hunk, same context\), it automatically applies the recorded resolution. This is crucial for maintaining feature branches that live for weeks. The resolution database is stored in \`.git/rr-cache/\`. It can be explicitly triggered with \`git rerere\` after a failed merge.
