[codey] Detect prefixed MCP config examples

[Conalh]

Summary

• Detect exact prefixed MCP config example filenames (example_mcp_config.json, claude_mcp_config.json, cursor_mcp_config.json, vscode_mcp_config.json) as sample/example MCP drift.
• Keep these findings separate from active MCP server drift and avoid broad registry/backup filename matching.
• Prepare v0.1.11 docs/package metadata and committed dist runtime for release.

Closes #34.
