fix: MCP server validation script - detect running servers properly

- Fixed validation logic to properly detect MCP server startup
- Added checks for stdout indicators (server-started, SUCCESS, ready)
- Added health checks to verify servers stay running (MCP servers don't exit)
- Fixed EPIPE error by checking if process is alive before killing
- All 16 StrRay MCP servers now pass validation locally and in CI
- CI uses longer timeouts (30s spawn, 10s startup) vs local (10s spawn, 2s startup)

MCP servers are working correctly - validation script was the issue.
