Implements GitHub Copilot as an AI provider (Issue athasdev#573) using OAuth device flow for authentication instead of static API keys. The Copilot chat API is OpenAI-compatible, with a two-step token chain: GitHub OAuth token (stored in keychain) exchanged for a short-lived Copilot API token (cached in Rust memory with 5-min expiry buffer). Rust backend (5 Tauri commands): - copilot_start_device_flow: initiates GitHub OAuth device flow - copilot_poll_device_token: polls for user authorization - copilot_get_auth_status: checks if authenticated - copilot_get_api_token: gets/refreshes Copilot API token with caching - copilot_logout: removes OAuth token and clears cache TypeScript provider: - CopilotProvider with buildHeadersAsync() for dynamic OAuth headers - Dynamic model fetching via Copilot API /models endpoint - OpenAI-compatible payload format UI: - CopilotAuthModal for device code OAuth flow (copy, countdown, polling) - Settings page replaces 'Coming Soon' with Sign In/Connected as UI - Provider model selector shows Authenticate/Sign Out for Copilot - CopilotIcon added to provider icons Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
