APTMetadataAdapter.fetch from on_button_pressed into a Textual worker,
performing all blocking fetches there before updating the UI; keep UI mutations
on the main event loop and preserve the existing metadata update behavior.
- Line 79: Update the metadata-loading loop around APTMetadataAdapter.fetch to
increment a loaded_count only when fetch returns usable metadata, then report
loaded_count instead of len(packages) in the “Loaded metadata” log message.

Move APT metadata loading to a Textual worker.
on_button_pressed calls APTMetadataAdapter.fetch synchronously for each package. The method runs subprocess.run(..., timeout=10), so the UI event loop can block for up to 10 seconds per package. Run the metadata loop in a Textual worker before updating the UI.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Report the number of successful metadata fetches.
APTMetadataAdapter.fetch can return None when apt-cache show fails or returns no usable metadata. The loop still reaches line 79, which reports all requested packages as loaded. Track successful fetches with loaded_count.
Proposed fix

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Enable and validate the metadata path in this test.
The test suite installs the TUI dependency and runs tests/ in CI, but this test leaves #metadata disabled. Therefore, it does not cover the metadata branch. isinstance(out, str) also passes when the handler catches an exception and leaves "Results will appear here." unchanged. Set #metadata to True and assert that the result is not the initial placeholder.
