🧹 Fix swallowed error in sidepanel.js executeScript catch block

[google-labs-jules]

🎯 What: Added console.warn(injectionErr) inside the previously empty catch block for content script injection in extension/sidepanel/sidepanel.js.
💡 Why: Silently swallowing errors makes debugging difficult. Logging the error improves observability and maintainability without altering functionality.
✅ Verification: Verified that tests pass via ./test/test-extension.sh and requested a code review.
✨ Result: A safer, more debuggable codebase.

Duplicate of #93. 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 now obsolete and stopping work on this task.
