plugin: a plugin names its own icon and the key field's title and hint (Lemon on Discord) — a plugin's provider took only the market's icon, and an api method's key field always read "<name> API key" with no hint. auth.icon (or package.json "magpie": {"icon"}) as an https URL, fetched once through the public-only icon path, or a data:image URI now comes before the market icon; an api method's label titles the key field as in OpenCode, and a new placeholder hints it, in the window and in magpie plugin login. README has a For plugin authors section. TestPluginOwnIcon, TestPluginOwnIconAndKeyHint and plugin-key-hint.test.cjs (Chromium, WebKit, en/zh) fail without the change.
