Update chat-plugin to support model-proxy

[zhogu]

This pull request refactors the chat plugin to simplify model selection and API interactions by removing job-based model fetching and related state. The code now fetches all available models directly from a unified model proxy endpoint, eliminating the need for job management logic. This streamlines the user interface and backend logic, making the codebase easier to maintain and understand.

Major refactoring and simplification:

• Removed all job-related logic and state from the frontend, including the Job type, job selection UI, and associated API calls. The application no longer fetches or manages jobs, focusing solely on model selection. [1] [2] [3] [4] [5] [6] [7]

API and state management changes:

• Replaced job-based model fetching (fetchModelsInCurrentJob) with a new fetchAllModels function that retrieves all models from a single model proxy endpoint, updating related API calls and state accordingly. [1] [2]
• Updated chat request and streaming functions to use the unified model proxy endpoint and removed job-dependent parameters. [1] [2] [3]

Component and prop updates:

• Updated the main App component and plugin initialization to remove job server and token props, reflecting the new simplified model. [1] [2] [3]

These changes collectively result in a cleaner, more maintainable codebase focused on direct model selection without the complexity of job management.

The refactoring eliminates the complexity of managing jobs, job servers, and associated state, streamlining both the UI and backend logic to focus solely on direct model selection.

Key Changes:

• Removed all job-related state, types, and UI components, including job selection dropdowns and job server configuration
• Replaced job-based model fetching with a single fetchAllModels function that queries a unified model proxy endpoint
• Updated API functions to use the model proxy path instead of job-specific endpoints for chat requests
