Add VertaFlow technology

[Designed-By-Anthony]

Summary

Adds the parent VertaFlow platform technology entry.

The repository already contains VertaFlow widget-level detections for Analytics, Booking, Chat, and Forms. This adds the main VertaFlow CRM/commerce platform detection for sites that use the hosted pixel, client portal, or tenant app shell.

Detection signals

• scriptSrc: api.vertaflow.io/v1/pixel.js
• dom: first-party pixel script with data-site
• html: window.__TENANT_CONFIG__= for tenant portals
• html: Powered by VertaFlow portal footer

Example sites

Per the contribution guide, here are 10 live URLs with matching signals:

1. https://vertaflow.io

Validation

• Parsed src/technologies/v.json as JSON.
• Validated src/technologies/v.json against schema.json using Ajv 2020.
• Ran a local evidence matcher against the 10 URLs above; all 10 matched either the pixel script or tenant portal markers.
