v4.1.4

Fixed

• apltk codegraph --help without @colbymchenry/codegraph: findProjectRoot() moved after --help checks so that help output works without the optional dependency installed. Previously it crashed with MODULE_NOT_FOUND because the handler tried to load the module before checking for help flags.
• @colbymchenry/codegraph not found in global installs: Added as optionalDependencies in root package.json so npm install -g @laitszkin/apollo-toolkit includes it when available.
• rewrite-imports.mjs missing codegraph from tool names list: The postbuild script's hardcoded TOOL_NAMES list omitted codegraph, causing isKnownToolName('codegraph') to return false in CI-built packages.
