- New merge-upstream job: creates branch, merges upstream, runs Claude
agent mode to review, resolve conflicts, run tests, and create a PR
- Dynamic fork impact analysis: computes overlap between fork-modified
files and upstream-changed files to assess conflict risk
- Claude reviews ALL upstream changes for fork compatibility (renamed
imports, changed APIs, GitHub-only assumptions) not just conflicts
- Maintainability principle: minimize fork divergence, prefer adapters
- Remove ANTHROPIC_API_KEY (using OAuth token only)
