Automate security incident triage with GPT-4o-mini and Gmail notifications

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

Automatically triages inbound security findings (e.g., from AWS Security Hub via EventBridge → SNS → Webhook), classifies them with an LLM, generates a 3-step remediation plan, and emails a compact incident brief.

Pipeline: Webhook → CleanFinding (normalize) → Classify (LLM) → Plan (LLM) → Gmail (email). You can substitute Microsoft Teams, Slack, etc.

- Normalizes the incoming finding JSON (title, description, account, resource id/type, updatedat).

- Uses an LLM to assign incidenttype, severity (P0--P3), urgency, shorttitle, and why (concise rationale).

- Produces a 3-step remediation plan with ownerhint and successcriteria---kept atomic and practical.

- Sends a clean HTML email with all details (subject line includes short title, resource, and account).
