* ContextService - Context window management and limit checking
*
* This service provides context window monitoring and limit checking using real-time

* current usage and calculating available space for new content.
*
* **Architecture & Relationships:**
* - **ContextService** (this class): Context limit monitoring
* - Uses SlotsService for real-time context usage data
* - Calculates available tokens with configurable reserves
* - Provides context limit checking and error messaging
* - Helps prevent context window overflow
*
* - **SlotsService**: Provides current context usage from server slots
* - **ChatStore**: Uses context checking before sending messages
* - **UI Components**: Display context usage warnings and limits
*
* **Key Features:**
* - **Real-time Context Checking**: Uses live server data for accuracy
* - **Token Reservation**: Reserves tokens for response generation
* - **Limit Detection**: Prevents context window overflow
* - **Usage Reporting**: Detailed context usage statistics
* - **Error Messaging**: User-friendly context limit messages
* - **Configurable Reserves**: Adjustable token reservation for responses
*
* **Context Management:**
* - Monitors current context usage from active slots
* - Calculates available space considering reserved tokens
* - Provides early warning before context limits are reached
* - Helps optimize conversation length and content
