copilot command #766

[cmendible]

Description

This pull request introduces a new "Copilot" AI assistant feature to Azure Quick Review (azqr), enabling natural language interaction with azqr tools via GitHub Copilot. It adds a new CLI command, interactive TUI, and supporting infrastructure, along with documentation and dependency updates.

Copilot AI Assistant Integration

• Added a new copilot command to the CLI (cmd/azqr/commands/copilot.go), supporting interactive sessions, single-prompt mode, and model selection. Also includes a subcommand for listing available models.
• Implemented an interactive TUI console for Copilot-powered sessions, including styled output, prompt handling, and streaming responses (internal/copilot/console.go).
• Defined a custom agent configuration for azqr, providing the assistant with domain-specific tools, orchestration rules, and post-scan presentation logic (internal/copilot/agents.go).
• Added configuration management for Copilot user preferences, such as model and mode (internal/copilot/config/config.go).

Documentation Updates

• Updated README.md and usage documentation to describe the Copilot assistant, prerequisites, commands, and available tools. [1] [2]

Dependency Updates

• Added new dependencies for Copilot SDK, TUI, and related libraries in go.mod (e.g., github.com/github/copilot-sdk/go, github.com/charmbracelet/lipgloss, github.com/chzyer/readline). Updated several indirect dependencies to support the new features. [1] [2] [3] [4]
