feat(cli): publish runfusion.ai npm alias, lead install with npx runfusion.ai

Add a 633-byte shim package at packages/cli-alias/ published to npm as
`runfusion.ai@0.0.1`. Bare `npx runfusion.ai` boots the dashboard;
subcommands forward to the underlying @runfusion/fusion CLI so
`npx runfusion.ai task list` etc. Just Work. Both `runfusion.ai` and
`runfusion` bin names are exposed.

READMEs now lead the install story with `npx runfusion.ai` — the
shortest zero-install entry — and keep the longer `npx @runfusion/fusion
dashboard`, curl installer, Homebrew, and npm-global paths below.

+# runfusion.ai
+
+Launch [Fusion](https://runfusion.ai) with a single npx:
+
+```bash
+npx runfusion.ai
+```
+
+That command boots the Fusion dashboard and AI engine on port 4040. Prints an `Open:` URL with a bearer token you can click to open in your browser.
+
+## Subcommands
+
+With no arguments, `runfusion.ai` defaults to `dashboard`. Any other subcommand is forwarded to the underlying [`fn` CLI](https://www.npmjs.com/package/@runfusion/fusion):
+
+```bash
+npx runfusion.ai                     # → fn dashboard
+npx runfusion.ai task create "fix X" # → fn task create "fix X"
+npx runfusion.ai --help              # → fn --help
+```
+
+## How it relates to `@runfusion/fusion`
+
+This package is a ~1 KB alias. It declares `@runfusion/fusion` as a dependency and its `bin` delegates to the same entrypoint. Use whichever name reads better:
+
+```bash
+npx runfusion.ai
+npx @runfusion/fusion dashboard
+```
+
+For persistent installs, prefer Homebrew or `npm install -g @runfusion/fusion`.
