PTLam Agent OS Code Style Dart Flutter

Rules for Dart and Flutter code: SDK and package resolution, analyzer and formatter settings, naming, library layout, data types, failures, async work, and dartdoc; then the four-layer feature structure, presentation state, widgets, routes, external boundaries, localization, and tests; then the PTLam Agent OS src/app monorepo's package kinds, Melos commands, cross-package composition, and test-level order. This skill owns Dart, Flutter, and monorepo mechanics; the foundation owns everything else.

Required skills

Reason: Provides the language-neutral conventions and testing doctrine the Dart, Flutter, and monorepo mechanics satisfy. This skill does not repeat them.

Instructions: Loading the foundation is required, not optional background.
