### Platform Improvements

#### Chart Visualization Fixes

* **Crash Prevention** - Fixed app crashes when charts reference missing files or invalid data sources
* **Line Chart Data Accuracy** - Resolved incorrect data display issues in line chart visualizations
* **Hover Interaction** - Fixed hover-over dots positioning - now correctly responds to hovering over any point on the line with accurate data display

#### Semantic Layer Improvements

* **Sidebar Scrolling** - Restored scroll functionality in semantic layer sidebar that was previously broken
* **Toggle Button Fix** - Fixed expand/collapse toggle for views with improved state management using null-initialized pattern for proper "all expanded" default state
* **TypeScript Type Safety** - Added explicit type annotations to callback parameters in utility functions

#### Configuration and State Management

* **Environment-Based State Directory** - Fixed state directory not being picked up from environment variables, preventing data loss from temporary directory usage
* **Proper Data Persistence** - State directory now correctly inferred from environment configuration

#### Dependencies and Infrastructure

* **Docker Improvements** - Upgraded Bollard Docker client with improved options and capabilities
* **Dependencies Update** - Updated Rust and all dependencies to latest versions for improved performance and security
