What does this do?

Adds integration documentation for connecting Perplexity Pro as an MCP client to Open Brain. Provides step-by-step instructions for configuring the Bearer auth connection (introduced in the companion server PR), enabling Perplexity to search and capture thoughts directly. The four MCP tools (search_thoughts, list_thoughts, thought_stats, capture_thought) become available in Perplexity.
