Greptile Summary

Adds Docker image pulling, registry digest-based update checks, cache invalidation, status badges, and configurable table pagination.

• Adds local and remote image pull actions with loading and refresh behavior.
• Compares local image metadata with registry digests using bounded concurrency and a 24-hour server-side cache.
• Adds update-state presentation, manual checks, dangling-image handling, and rows-per-page controls.

Confidence Score: 5/5

The PR appears safe to merge with no concrete blocking or independently actionable issues identified.

The new Docker image operations preserve server organization checks, quote image references, bound registry-check concurrency, and degrade lookup failures to an explicit unknown status.
