This commit introduces the foundational elements of the new Stream Design System and a comprehensive gallery application (Widgetbook) for showcasing and customizing components.
**Core Package (`stream_core_flutter`):**
* **Design Tokens**: Added foundational design tokens for colors, spacing, radius, typography, and box shadows. These tokens are organized into primitive and semantic layers.
* `StreamColors`: Defines the primitive color palette.
* `StreamColorScheme`: Provides semantic color roles (e.g., `accentPrimary`, `textSecondary`).
* `StreamTypography`, `StreamTextTheme`: Defines font primitives and semantic text styles.
* `StreamSpacing`, `StreamRadius`, `StreamBoxShadow`: Adds tokens for layout and elevation.
* **`StreamTheme`**: Implemented a new `ThemeExtension` to aggregate all design tokens and component themes, enabling centralized theming.
* **New Components**: Added `StreamAvatar`, `StreamAvatarStack`, and `StreamOnlineIndicator`.
* **Theming Infrastructure**: Added `theme_extensions_builder` to auto-generate `copyWith`, `lerp`, and `==`/`hashCode` for theme classes.
**Design System Gallery (`design_system_gallery`):**
* **Gallery App**: Replaced the basic Widgetbook setup with a new, fully-featured gallery application (`StreamDesignSystemGallery`).
* **Theme Studio**: Added a "Theme Studio" panel for real-time customization of all `StreamColorScheme` properties.
* **Enhanced Previews**:
* Added a toolbar with controls for device selection (`DeviceFrame`), text scaling, and light/dark mode toggles.
* Created a `PreviewWrapper` to apply theme, device frame, and text scale to all use cases.
* **New Use Cases**:
* Added comprehensive use cases for new components (`StreamAvatar`, `StreamAvatarStack`, `StreamOnlineIndicator`).
* Added showcases for semantic tokens (`Typography`, `Elevations`).
* Improved `StreamButton` use cases with more variants and real-world examples.
* **Agent Guide**: Added `AGENTS.md`, a guide for AI agents on contributing to the gallery.

The `StreamButtonTheme` and its related data classes have been removed from the core theme structure. This simplifies the theme by removing the button-specific theming. Additionally, the `lerp` function for `StreamBrandColor` has been adjusted, and `StreamAvatarColorPair` is now generated using `themeGen`.
