v0.7.0 — version badge by the app name, feedback footer

Added

• The installed version is shown next to the app name on every surface — popup, settings, annotation view and recorder — so you can name your build when reporting a problem without opening chrome://extensions. The badge is selectable as one unit for easy copying.
• A footer in the annotation view, where a report has just been finished: a link to rate the extension in the Chrome Web Store, and a link to request a missing feature on the project page.

Fixed

• The E2E check for the project-domain gate was flaky: it slept for a fixed time while waiting on an asynchronous chrome.storage write and the content script that reads it. It now polls for the actual conditions. A test that only sometimes passes reports nothing.
