Add n8n social research and capability workflows

[erickkkyt]

Summary

• Add an importable Search → Inspect → Run workflow for current BeatAPI capabilities, including text, image, video, Social Data, and Web Search discovery.
• Add three specific Social Data research workflows: X keyword conversations, Instagram profile comparison, and YouTube comment themes. They use built-in HTTP Request nodes and generate reviewable draft summaries with source IDs.
• Document how to use BeatAPI text models with n8n's built-in OpenAI Chat Model and a custom Base URL, while using HTTP workflows for asynchronous image and video models.

Verification

• npm run verify passed: 30 Node tests, 7 Python tests, shell/Python checks, and OpenAPI lint.
• All four new workflows were imported successfully with local n8n 2.40.7 on Node 24.
• The X keyword workflow executed successfully end to end in a temporary local n8n instance with a temporary credential. No credential is present in the committed exports.
• Live BeatAPI calls verified the X search, both sample Instagram profiles, YouTube comments, and the /v1/models directory. The Instagram and YouTube workflows have import and response-shape coverage; their complete n8n executions remain to be run.

These are GitHub examples. Submission to n8n's Creator Portal is a separate review step.
