docs(readme): show what Object UI renders + slim and reposition (#1982)

- Add a "What is Object UI?" section positioning it as the View layer of the
  ObjectStack ecosystem (describe / render / run); standalone like Amis/Formily
- Add a JSON-schema -> rendered-UI hero and a "See what it renders" gallery
  (dashboard, Gantt, kanban, calendar) + the visual designers — the README had
  no UI screenshots, only badges
- Fix the published-vs-not-published contradiction; drop the duplicate
  "Quick Start (Development Mode)" (Development Setup covers source)
- Remove unverifiable marketing claims and the version-specific "What's New" block
- Surface the agent skill (npx skills add) in Community

-## 🎉 What's New (v3.3.x line)
+## What is Object UI?
 
-**v3.3.0 was the first official release** — all 39 packages under `packages/*` are published to npm. The current published patch is **v3.3.2** and the workspace now consumes **`@objectstack/spec` ^4.0.4** and **`@objectstack/client` ^4.0.4** (the UI sub-export remains backward compatible with the 3.3.x renderer).
+**Object UI is the View layer of the [ObjectStack](https://github.com/objectstack-ai/framework) ecosystem** — a standalone, schema-driven renderer that turns a JSON schema (or ObjectStack metadata) into production-grade React UI. Use it on its own with any backend, like Amis or Formily — or let it render ObjectStack apps end to end.
 
-> Unreleased work is queued in `.changeset/` and visible in `CHANGELOG.md`'s
-> `[Unreleased]` section — see "Recent Highlights" below.
-
-### Recent Highlights (post-3.3.2, queued for next release)
-
-- 📱 **Mobile UX rounds 1 & 2** — kanban readability, calendar default view on phones, timeline marker clipping, list/sidebar/record-detail polish (`apps/console`, `plugin-kanban`, `plugin-calendar`, `plugin-timeline`).
-- 🪟 **Manage Views dialog** (`@object-ui/plugin-view`) replaces inline tab drag for view CRUD.
-- 🧭 **App-shell view-tab strip** now renders for single-view objects too; broken DropdownMenu propagation fixed.
-- ⚡ **View metadata merging + request coalescing** — duplicate `find()` queries from concurrent renderers are deduped.
-- 🌐 **Convention-based i18n for sidebars, breadcrumbs, charts, tables, dashboards** — translation packs can localize every label without editing metadata.
-- 🛠️ **MetadataProvider lazy loading** — Console no longer fetches the entire `app/object/dashboard/report/page` graph on boot.
-
-### Highlights
-
-- 📦 **39 published packages** with complete release metadata, per-package `LICENSE` and `CHANGELOG.md`
-- 📚 **Refreshed documentation** across every package README and the [objectui.org docs site](https://www.objectui.org)
-- 🏗️ **Thin integration packages** — `@object-ui/app-shell` and `@object-ui/providers` enable third-party integration in ~50KB instead of pulling the full console
-- 🔌 **Spec v4 alignment** — plain-string `label` types across Navigation schemas, Protocol bridges updated
-- 🧠 **Unified Agent Skill** — `npx skills add objectstack-ai/objectui` installs a consolidated skill (works with Claude Code, Cursor, Codex, GitHub Copilot, Windsurf, Gemini, Cline). See [`skills/objectui/`](./skills/objectui/) and [skills.sh](https://skills.sh/objectstack-ai/objectui).

-### Component Namespaces
-Organize components into namespaces to prevent naming conflicts:
-```typescript
-ComponentRegistry.register('button', ButtonComponent, {
-  namespace: 'ui'  // Prevent conflicts across plugins
-});
 ```
-
-### Lazy Field Registration
-Load only the fields you need for 30-50% smaller bundles:
-```typescript
-import { registerField } from '@object-ui/fields';
-
-// Only load what you use
-registerField('text');
-registerField('number');
+Describe  →  ObjectStack   the metadata protocol
+Render    →  Object UI     this repo — JSON / metadata → React UI
+Run       →  ObjectOS      the runtime
 ```
 
-### Build Performance
-- **3-5x faster CI builds** with Turbo v2
-- **Parallel package builds** with intelligent caching
-- **Instant rebuilds** for unchanged packages
-
-👉 See [CHANGELOG.md](./CHANGELOG.md) for the full 3.3.x release notes and the `[Unreleased]` section.

-    # Build the core engine
-    pnpm build
-    ```
-
-2.  **Run the ObjectStack Console**
-
-    Start the unified development console to preview your apps and objects:
-
-    ```bash
-    pnpm dev
-    # Opens http://localhost:5173
-    ```
-
-3.  **Try the BYO-Backend Console Example** (New!)
