refactor: share the default tool services between surfaces

Move the composition of the default tool services from the Node MCP
server into gods-eye-view/tools/services, a portable export. Given a
fetch that resolves the sources' /api paths, it builds the same services
in a browser as on the local MCP server, so other surfaces can compose
the same catalog. Queries still read only their services.
