feat: component execution via Worker fetch + API recipes

- Logic components (15): each deployed as Worker at {name}.arcrun.dev,
  cypher-executor fetches them via HTTP POST
- API components (6): gmail, telegram, line_notify, google_sheets,
  http_request, cron executed inline via fetch recipes in component-loader
- External URL support: any https:// componentId is fetched directly
  (n8n webhooks, MCP endpoints, etc.)
- Add deploy-logic-components.sh script for building/deploying WASM Workers
- Add component-worker-template with inline WASI shim
