feat(google_news): implement Google News MCP server via SerpAPI

[applebar17]

Description

Implemented a new Google News MCP server backed by SerpAPI. This PR adds:

• Three atomic tools:

  • google_news_search_news (keyword search)

• Dual transports: SSE (/sse) and StreamableHTTP (/mcp), with optional one-shot JSON mode (--json-response)

• Pydantic models for request/response schemas, request-body logging probe, and robust error/rate-limit handling

• Dockerfile, README, and PowerShell/Python test snippets

This server was written as part of a coding exercise for a Founding Engineer position in the SF Bay Area. I’d be happy to meet and walk through the design or answer any questions.
