Workflow file key mismatch prevents accessing demo workflow

What fails: The allWorkflows object in _workflows.ts uses key 'workflows/0_calc.ts' but the actual file is named 0_demo.ts, making the demo workflow unreachable.

How to reproduce:

1. Start the server with the workbench/express application
2. Make a request to /api/trigger?workflowFile=workflows/0_demo.ts&workflowFn=simple

Result: Returns 400 error: {"error": "Workflow file \"workflows/0_demo.ts\" not found", "status": 400}

Expected: Should successfully load and execute the demo workflow module from workbench/express/workflows/0_demo.ts

Root cause: In _workflows.ts line 12, the dictionary key was 'workflows/0_calc.ts' but no such file exists. The import at line 1 correctly points to './workflows/0_demo.js', and the actual file on disk is workflows/0_demo.ts. The lookup in trigger.routes.ts line 19 uses allWorkflows[workflowFile] which fails when users request the actual file name.

Fix: Changed line 12 from 'workflows/0_calc.ts': demo, to 'workflows/0_demo.ts': demo, to match the actual file name and import source.
