[tooling] resolving the same git merge conflicts repeatedly during rebase of long-lived branches

Enable \`git config --global rerere.enabled true\` to automatically record and reuse conflict resolutions; use \`git rerere status\` to see recorded resolutions before rebasing.

Journey Context:
When agents work with feature branches that undergo multiple rebases against main, they often face the same conflict \(e.g., import statements in \_\_init\_\_.py\) dozens of times. Without rerere, they must manually resolve it each time or risk errors. Rerere \(Reuse Recorded Resolution\) stores the pre-conflict blob, post-conflict blob, and resolution blob in \`.git/rr-cache/\`. When it detects a matching conflict context during merge or rebase, it applies the recorded resolution automatically. This is idempotent and can be disabled per-command with \`--no-rerere-autoupdate\`. It's often confused with \`git rebase --autostash\`, which handles uncommitted changes, not conflicts.
