* Read .mcp.json from the project root (cwd) and return servers not already
* discovered by mcporter. This bridges the gap where mcporter doesn't scan
* the standard .mcp.json config used by Claude Code, Cursor, etc.
* Read MCP server configs from project-level files (.mcp.json and .gsd/mcp.json)
* and return servers not already discovered by mcporter.
*
* Search order:
* 1. .mcp.json (Claude Code / Cursor standard)
* 2. .gsd/mcp.json (GSD-specific per-project config, #716)
*
* Project config overrides global — servers found here take precedence over
* identically-named servers from mcporter's global discovery.
