The toolbar badge now also counts banners hidden by Crumb's generic rules —previously it only ticked up on sites with a dedicated rule. Popup wording reflects which kind of rule fired (site, generic, or none).

Adds a popup (popup.html/.css/.js) wired up via action.default_popup. The popup queries the active tab via browser.tabs.query and asks the existing content script for status with a one-shot crumb:status message — no remote calls, no new permissions. Existing <all_urls> host permission is sufficient. inject.js was updated to track which cosmetic-map key matched and to register the status responder on the top frame even when no rule matches, so the popup can distinguish loading state from no-rule state.

Icon polish — fixed a white halo around the icon on Firefox's dark toolbar by making the icon background properly transparent. No functional changes.

Toolbar badge. A green number on the Crumb icon now shows how many cookie-banner elements are being hidden on the current page — so you can tell at a glance that it's working. Per-site rules only; the badge stays empty when only the generic stylesheet fires. No new permissions, nothing new leaves your browser.
