* refactor: add top level resolve symlinks script

* fix: cleanup builder directories (#319)

* fix: add sveltekit server routes to builder

* fix: remove root workflow dir check

* fix missing root level workflow route

* Fix: The constructor now hardcodes `dirs: ['src/routes', 'src/lib']` which silently ignores any user\-provided `dirs` option passed to the plugin\, breaking the documented API and removing support for custom workflow directories\.

* Fix: The test expectations don\'t match the new implementation of `getWorkflowDirs()`\. The mock provides `scanDirs` which the new code no longer uses\, and the new implementation adds scanning of `routesDir` and `apiDir` instead\.

* fix(nitro): use src dir

+
+Start the $ARUGMENTS workbench (default to the nextjs turboback workbench  available in the workbenches directory). Run it in dev mode, and also start the workflow web UI (run `npx workflow web` inside the appropriate workbench directory).
+
+Then trigger the 7_full.ts workflow example. you can see how to trigger a specific example by looking at the trigger API route for the workbench - it is probably just a POST request using bash (maybe curl) to this endpoint: <http://localhost:3000/api/trigger\?workflowFile\=workflows/7_full.ts\&workflowFn\=handleUserSignup>>
