## Overview

This release brings significant performance optimizations and stability enhancements. We fixed a critical bug in the client management logic, eliminating the 1-2s process startup latency between turns and significantly improving Time to First Token (TTFT). Additionally, the plugin now supports a pure BYOK mode and features improved environment isolation for concurrent user requests.

## New Features

- **🔑 Pure BYOK Mode**: Allows the plugin to operate without a `GH_TOKEN` by using custom API keys (OpenAI/Anthropic) via BYOK Valves.
- **🩺 Smart Stall Detection**: Integrated `client.ping()` into the timeout logic. The system now "pokes" the underlying process before aborting, preventing the termination of slow but healthy long-running tasks.
- **🧹 Smart TODO Visibility**: The TODO List widget is now automatically hidden in subsequent chats once all tasks are marked as completed, keeping the UI clean.

## Bug Fixes

- **🚀 Major Performance Optimization**: Fixed a regression where the shared singleton client pool was incorrectly terminated after each response. Restored 1-2s startup speed for all follow-up messages.
- **🛡️ Cross-user Isolation**: Redesigned environment variable injection to prevent token pollution during concurrent requests from different users.
- **📏 RichUI Height Stability**: Fixed the infamous infinite vertical growth bug in embedded HTML components by refining the height measurement and breaking the ResizeObserver feedback loop.

## Migration Notes

- If you previously relied on `GH_TOKEN` for standard Copilot models but want to switch to a pure BYOK setup, you can now safely clear the `GH_TOKEN` Valve and only configure `BYOK_BASE_URL` and `BYOK_API_KEY`.
