fix(FN-3888): resolve dependency-graph plugin from src in dashboard build

The dashboard dynamically imports `@fusion-plugin-examples/dependency-graph/dashboard-view`, which resolved through the plugin's package.json exports to `dist/`. When plugin source was edited without rebuilding, stale `dist/` (extensionless ESM imports) made the import throw and the UI surfaced "Bundled plugin view unavailable". Add vite/vitest aliases mapping the plugin (and its `/dashboard-view` subpath) to `src/` so the dashboard never depends on `dist/`. Mirrors the existing pattern for hermes/openclaw/paperclip runtimes. Also extends the runtime-plugin alias regression test, and emits `.js` extensions from the plugin source for the CLI-bundled path.
