Extension options easily accessible via standard browser extension menu

Extensions that bury settings inside the popup — with no options_page or options_ui entry in the manifest — force users to discover configuration through trial and error. Right-clicking the extension icon yields only Chrome's default context menu entries; settings are unreachable through the standard path users expect. Users who lose or reset their popup state cannot recover their preferences, and enterprise administrators managing deployed extensions have no canonical settings surface to document. Discoverability collapses and advanced features go unused.

Declare options_ui in manifest.json so Chrome exposes an Options entry in the standard extension context menu, and add a settings link in the popup so users discover it from either path. Prefer embedded options over open_in_tab: true for simple settings:

{ "options_ui": { "page": "options.html", "open_in_tab": false } }

Wire the popup link with chrome.runtime.openOptionsPage() in popup.js.
