docs: position manifest-local as fork's OpenClaw integration path

Upstream removed both plugin packages (mnfst#1527, mnfst#1528) and local mode
(mnfst#1539) in favor of Docker-only self-hosting. This fork preserves local
OpenClaw support via manifest-local, which fixes the embedded NestJS
architecture that motivated upstream's deprecation.

+### OpenClaw Plugin (this fork)
+
+Upstream removed both OpenClaw plugin packages ([#1527](https://github.com/mnfst/manifest/pull/1527), [#1528](https://github.com/mnfst/manifest/pull/1528)) and local mode ([#1539](https://github.com/mnfst/manifest/pull/1539)) in favor of Docker-only self-hosting. This fork preserves and improves the local OpenClaw integration via **`manifest-local`** — a new plugin that fixes the architectural problems that led upstream to abandon the plugin approach.
+
+**What changed:** The old `manifest` plugin embedded a full NestJS server inside the OpenClaw gateway process, causing double-boot races, orphan processes, and SQLite locking. `manifest-local` solves this by running the backend as a **separate detached process** (14.8 KB plugin, zero runtime deps).
+
+```bash
+# Clone this fork and build
+git clone https://github.com/andychu666/manifest.git
+cd manifest && git checkout openclaw-plugin-v5.45.1
+npm install && npm run build
+
+# Install in OpenClaw
+openclaw plugins install --path ./packages/openclaw-plugins/manifest-local
+openclaw config set plugins.entries.manifest-local.enabled true
+openclaw gateway restart
+```
+
+Dashboard: [http://localhost:2099](http://localhost:2099). Full docs: [`packages/openclaw-plugins/manifest-local/README.md`](packages/openclaw-plugins/manifest-local/README.md).
+
+> **Note:** The old `packages/openclaw-plugins/manifest` and `packages/openclaw-plugins/manifest-model-router` packages follow upstream's deprecation and are no longer maintained in this fork. Use `manifest-local` instead.

 ## How it works
 
 Every request to `manifest/auto` goes through a 23-dimension scoring algorithm (runs in under 2ms). The scorer picks a tier (simple, standard, complex, or reasoning) and routes to the best model in that tier from your connected providers.
