Enrich new form leads with Lusha, HubSpot, and Slack alerts

Description

How it works
A webhook receives form submissions with an email address
The email is validated and checked against HubSpot for duplicates
Lusha enriches the lead with phone number, job title, seniority, and company data
Enriched data is merged with form fields and upserted into HubSpot CRM
An SDR is alerted on Slack and the webhook returns a JSON response

Set up steps
Install the Lusha community node (@lusha-org/n8n-nodes-lusha)
Add your Lusha API, HubSpot OAuth2, and Slack credentials
Point your form's action URL to the webhook endpoint
Configure the Slack channel for SDR alerts
