feat: load plugin frontends at runtime and remove plugin ids from the shell

+/**
+ * @termix/plugin-sdk/ui: the shell's components, for plugins.
+ *
+ * Everything exported here is public API. A plugin builds its UI from these
+ * so it looks like the rest of the app and picks up theme changes, and it
+ * receives the shell's own instances through the import map, never a copy.
+ *
+ * The list is deliberate. It covers what the bundled plugins use today: the
+ * shadcn primitives, the composites for metrics, connection screens and
+ * settings rows, and the contexts a connection surface needs. Adding to it is
+ * a contract change; update ARCHITECTURE.md with it. Removing from it breaks
+ * plugins.
