🧹 Fix swallowed error in executeScript catch block

[google-labs-jules]

🎯 What: Modified extension/sidepanel/sidepanel.js to add a console.warn statement inside the catch (injectionErr) block for chrome.scripting.executeScript.
💡 Why: Silently swallowing errors makes debugging difficult when the extension fails to inject a content script (e.g. into restricted chrome:// URLs). Surfacing this as a warning in the console aids development and debugging without disrupting normal user flow.
✅ Verification: Verified the code diff and ran the entire Chrome Extension test suite via ./test/test-extension.sh, which passed successfully. Code review confirmed the safety and correctness of the change.
✨ Result: Improved maintainability and debugging capability for the sidepanel script without changing any existing application behavior.

Duplicate of #90. In #109 this catch in refreshActiveTab is the expected path when the panel has no activeTab grant for the tab yet (the user switched tabs without clicking the icon), so a warning here would fire on every tab switch.

Closing as part of triaging the open PRs against #109, which restructures the extension (it removes the .cjs twins, renames test/test-*.js to .mjs, and rewrites the crawler and side panel). It is up to date with main as of ee79db2.

Understood. Acknowledging that this work is a duplicate and superseded by PR #109, and stopping work on this task.
