Send organized security CVE digests from NVD with AI-polished summaries to Gmail

Summary -------

Turns the latest CVEs from NVD into a clean, sortable email digest (table + plaintext) and sends it via Gmail. The flow pulls the newest CVEs, extracts Vendor / Product / Version, severity & CVSS, highlights public exploit references, drafts an HTML table, then asks OpenAI to tighten the copy before emailing it. Optionally, you can swap the Gmail node to Signal, Slack, Microsoft Teams, etc.

Perfect for: SecOps leads who want a low-noise digest of what changed recently, grouped and ranked by severity.

What this workflow does -----------------------

- Triggers on a schedule (every 30 minutes by default).

- Calls the NVD 2.0 API to fetch recent CVEs.

- Parses each CVE to extract:

- Vendor / Product / Version(s) (from CPE 2.3 where available, with a text fallback)
