Feature Request: Add Agent Management Section and Group Models by Provider in Settings

Agent Management System

Problem: The settings currently lack a dedicated section for managing agents (adding, editing, and configuring them). This makes the overall workflow and purpose of agents unclear to the user.

Proposed Solution: Add a new "Agents" section in the settings interface, implement full CRUD (Create, Read, Update, Delete) functionality for agents, and provide visual indicators showing how each agent operates within the system.

Model Grouping by Provider

Problem: The current flat list of models creates ambiguity when a user configures multiple providers offering the same model (e.g., running gpt-5.6 via both OpenAI and Azure). Distinguishing them purely by custom names is inefficient and prone to confusion.

Proposed Solution: Restructure the model selection UI into distinct blocks categorized by provider (e.g., OpenAI, Anthropic, Ollama, Azure) and group available models under their respective provider blocks to make source attribution clear.

Start in the settings interface and trace the existing model-selection UI and provider data flow. Implement the Agents section with create, read, update, and delete behavior plus operating-mode indicators, then group models into provider-specific blocks. Done means agents can be managed in settings and models with the same name remain distinguishable by provider.
