Note

Prevents caching blank page content and guards MutationObserver to start only when document.body is available.

• Page context (injected/src/features/page-context.js):
  • Observation Guard: Start MutationObserver only if document.body exists.
  • Cache Logic: Cache collection results only when content.content.length > 0 (skip empty content).

Pull Request Overview

This PR modifies the page context caching logic to prevent caching of blank or empty page content. The changes ensure that mutation observers only start when there is actual content to observe and that empty content is not stored in the cache.

Key changes:

• Added document.body check before starting mutation observer
• Conditionally cache content only when it contains actual data
