14974/// into the project file the moment any one server was added, edited, or
14975/// removed here, freezing that project's copy out of future changes to the
14976/// global definition. Unlike the hooks list (a plain `Vec` extended with no
14977/// dedup key), the merge for MCP servers is a name-keyed map — so this
14978/// couldn't duplicate or compound the way the hooks bug did, but it would
14979/// still quietly diverge project config from what the operator thought
14980/// they were changing. Mirrors `get_global_mcp_servers`, which has always
