Explain Diff

Explain what changed in each changed file.

Flow

1. Use user-provided diff source.
2. If source is missing, use unstaged changes.
3. If unstaged changes are empty, ask for source: staged, commit, range, branch, PR, or pasted diff.
4. Read diff.
5. Read surrounding code only when diff lacks context.
6. Explain every changed file.
7. Mention other files affected by each change.
8. Separate facts from inferred intent.
