Add src/index.ts so tsc produces dist/index.js

ClawHub upload rejected the package because package.json#main
('./dist/index.js') pointed at a file that didn't exist — tsc with
rootDir: 'src' was compiling src/plugin/*, src/api/*, src/engine/* but
not the root index.ts (which lives outside rootDir).

src/index.ts mirrors the root index.ts (re-exports the plugin default
plus the public API), so tsc emits dist/index.js. The root index.ts
stays for TS-direct loading via openclaw.extensions; the compiled
dist/index.js satisfies ClawHub and any host without TS support.
