AnySearch MCP

- Added support for agent-initiated user registration and instant API key issuance with a single email (no verification code required). - Expanded configuration instructions with agent-specific paths, improved compatibility notes, and clarified config keys for OpenCode and Claude Desktop. - Introduced required `X-Anysearch-Client` HTTP header for improved client/server interoperability; documented in all install examples. - Added security, license, and notice files; removed outdated documentation (`skill-card.md`). - Enhanced error handling documentation for API key registration flow, with explicit user messaging guidelines. - Updated vertical domain search instructions and removed references to hardcoded domain count.

OpenClaw 分析

This is a coherent remote search connector, but users should understand that AnySearch receives searches, extracted URLs/page content, and optional registration email/API-key data.
