Add ICBOMS (with open MCP / AI Agent API) to Part Search Engines - #159

Summary

Adds ICBOMS to the Part Search Engines section.

ICBOMS is an independent electronic component and semiconductor distributor providing electronics designers and procurement teams with a parametric semiconductor search engine, multi-line BOM quotation, datasheet lookups, and verified real-time distributor inventory.

🤖 Open MCP (Model Context Protocol) & AI Agent API

ICBOMS is one of the first semiconductor platforms with native Model Context Protocol (MCP) endpoints and machine-readable context:

• Machine-readable context: https://icboms.com/llms.txt
• MCP Search Endpoint: https://icboms.com/api/mcp/search?q={mpn} (returns structured JSON / Markdown tables for AI agents)
• MCP Product Facts: https://icboms.com/api/mcp/products/{mpn}
• MCP Parametric Comparison Matrix: https://icboms.com/api/mcp/compare?mpns={mpn1},{mpn2}
• OpenAPI Schema: https://icboms.com/openapi.json

This allows AI coding agents (Claude, Cursor, Antigravity) to query part specifications, footprint compatibility, and distributor stock programmatically.
