Semih 10dca2d3da plugin(telemetry-watcher): inline plugin SDK to break ESM TS chain ...

@fusion/plugin-sdk's package.json points its import entry at
src/index.ts (TS source), and that file imports core/src/plugin-types.js
via relative path. Node 22 ESM has no TS loader so the chain
unraveled at runtime: the plugin loader successfully resolved our
compiled dist/index.js, but the very first `import { definePlugin }
from "@fusion/plugin-sdk"` walked into TS source and fell over.

definePlugin is a pure typed identity function — it adds no runtime
behavior. Inline its source plus a structural copy of the plugin
context/route/manifest types we use, drop the @fusion/plugin-sdk
dependency entirely. The compiled output now imports nothing outside
node:crypto and Node builtins, so it can load anywhere fusion can
spawn ESM modules.

When fusion publishes a compiled SDK build, swap the inline types
back to import statements and restore the workspace dependency.
