Turnlight v0.9.0-beta

Turnlight v0.9.0-beta is the first public Windows beta installer for validation before a full 1.0 release.

Turnlight is a free, open-source, local Windows utility for long-running AI agent sessions. It watches a small screen region, detects a stable busy/stop -> ready/send transition, and shows a large alert when the agent is ready for the next prompt.

Turnlight runs locally: no accounts, no telemetry, no AI APIs, no cloud services, and no external services.
