Aiola v2.0.6: Android on Google Play, Cursor skill descriptions, analytics domain setup and Windows shell fixes

Android app is live: Settings → Connections now links to the Google Play listing instead of saying the Android app is still in review.

Cursor built-in skills show their descriptions: Skill files that write the description as a YAML block (>-, |+) rendered as a literal >-; the frontmatter parser now folds them.

Analytics setup asks for the site domain: Enabling analytics for a project takes the website domain up front, validates it, and shows the server's error instead of failing silently.

Windows shell controls: The back/forward and sidebar buttons sit over the collapsed rail on Windows instead of being offset for macOS traffic lights, and the collapsed sidebar no longer clips them.

Opening a drive root on Windows: Picking C:\ as a project folder is rejected with a message instead of creating a workspace with an empty name.

Setup completion is recorded: "Continue" on the setup page waits for the completion record before navigating, so a fresh install no longer looks unfinished on the next launch.

Sidebar unread badges: use the card background so they read on the flat shell.

Diff viewer worker: updated to the current @pierre/diffs build.
