Enhance ResponsiveRow/Col documentation and add tab view features (#129)

This pull request introduces version 7.5.23 and brings significant
improvements and documentation to the codebase, especially around the
`ThemedTabView` and the new responsive layout widgets. It includes bug
fixes, new features, comprehensive widget tests, and detailed skill
documentation for both Conventional Commits and responsive grid
components.

Key changes:

### ThemedTabView Improvements and Fixes
- Fixed multiple issues in `ThemedTabView`:
  - Removed a stray `debugPrint` statement from production code.
- Improved `initialPosition` handling by clamping out-of-bounds indices.
  - Eliminated unnecessary `setState()` calls in arrow button handlers.
- Ensured arrow button disabling state updates correctly during
navigation.
- Enhanced active-state detection to include alpha channel in color
comparison.
  - Refactored code to use named constants for magic numbers.
- Added the `wrapArrowNavigation` parameter for circular tab navigation,
allowing left/right arrows to wrap around tab boundaries.

### Testing Enhancements
- Added comprehensive widget tests for:
- `ThemedTabView` (covering rendering, navigation, callbacks, arrow
state, clamping, persistence, styles, and more).
- `ResponsiveRow` and `ResponsiveCol` (covering rendering, spacing,
alignment, builder usage, breakpoint logic, and integration).
  - `Sizes` enum (covering grid size and width calculations).

### Documentation Additions
- Added detailed skill documentation:
- For `ThemedTabView`, including parameter references, usage, best
practices, and testing.
- For `ResponsiveRow` and `ResponsiveCol`, covering parameters,
breakpoint logic, responsive behavior, best practices, and layout
patterns.
- For Conventional Commits, providing a thorough guide on semantic
commit message formatting, changelog impact, and best practices.

### Responsive Layout System
- Introduced `ResponsiveRow` and `ResponsiveCol` widgets, implementing a
Material 3 responsive 12-column grid system with breakpoint-based
sizing, spacing, alignment, and builder pattern support.

### Version Bump
- Updated the plugin version to 7.5.23.
