Specifics

• utils::package_manager_exec() auto-detects pnpm/yarn/npm -- JS modules should use this instead of hardcoding a package manager
• lint_cmd.rs is a cross-ecosystem router: detects Python projects and delegates to mypy_cmd or ruff_cmd
• vitest_cmd.rs uses the parser/ module for structured output parsing
• playwright_cmd.rs uses the parser/ module for test result extraction

Cross-command

• lint_cmd routes to cmds/python/mypy_cmd and cmds/python/ruff_cmd for Python projects
• prettier_cmd is also called by cmds/system/format_cmd as a format dispatcher target
