-/**
- * Produces a lightweight hash key for a list of file diffs.
- *
- * Intentionally excludes `diff.patch` — the extension never renders the
- * unified-diff patch string (VS Code's native diff editor uses before/after
- * file contents instead). Including it would pull in multi-MB payloads
- * generated by opencode's `context: MAX_SAFE_INTEGER` setting, inflating
- * memory for no benefit. The remaining fields (file, status, additions,
- * deletions, tracked, generatedLike, summarized, stamp) are sufficient to
- * detect when the diff list has meaningfully changed.
