fix: provide explicit git base branch reference to prevent PR review errors

- Tell Claude to use 'origin/{baseBranch}' instead of assuming 'main'
- Add explicit instructions for git diff/log commands with correct base branch
- Fixes 'fatal: ambiguous argument main..HEAD' error in fork environments
- Claude was autonomously running git diff main..HEAD when reviewing PRs
