Naiyuan Qing 66e99136c2 refactor(web): self-contained shadcn UI with base-nova style and design tokens
Migrate all shadcn components into apps/web/components/ui/ so the web app
is fully independent from packages/ui for its UI layer. Update to the
latest shadcn base-nova style. Add missing semantic color variables
(success, warning, info, canvas), font-mono mapping, scrollbar styling,
and wrap Select items in SelectGroup for proper padding.

/**
* Spinner — 3x3 grid pulse for **active processing / execution** states.

* Use when the system is actively doing work or waiting for human action
* (streaming content, generating responses, awaiting approval).
* For passive content-loading states, use `<Loading />` instead.
*
* Inherits color from `currentColor` (use Tailwind `text-*`).
* Scales with font-size (use Tailwind `text-*` for size).
