Greptile Summary

The PR refreshes the committed documentation search index and adds automation to regenerate it daily or on demand.

• Adds a serialized GitHub Actions workflow with write-only repository permissions needed to commit refreshed artifacts.
• Installs locked development dependencies and provides the OpenAI credential to the existing index builder.
• Commits regenerated vector and metadata files to main when their contents change.
• Updates the packaged index from 476 pages and 3,618 chunks to 497 pages and 3,979 chunks.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete changed-code defect identified.

The workflow supplies the documented build inputs, uses frozen dependencies, serializes its own runs, stages both generated artifacts together, and avoids creating a commit when the index is unchanged.
