Greptile Summary

This PR updates pinned CI and container dependencies. It changes:

• Docker release workflow action digests for Buildx setup, Docker Hub login, and image build/push.
• The Python slim Bookworm image digest used by both Docker build stages.
• The ghcr.io/astral-sh/uv:latest image digest used to copy uv and uvx into the builder stage.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
