OpenClaw Signals: Decoupled Rendering, Toast APIs, and Container Hardening

Tools

Core Notification API: claw toast Native Integration (PR #329)

This PR lands the core claw toast CLI command, finally giving users a native way to send real-time notifications from within the pipeline. It decouples notification logic from application code, meaning you can kill those brittle wrapper scripts you’re currently maintaining.

Headless Render: UI Decoupling for Background Processes (PR #328)

PR #328 strips the hosting dependency from the render loop, moving heavy lifting to the background renderer. This is a massive win for headless execution and automated testing, cutting down CPU overhead when you don't need a live viewport.

Deep Dive: Scheduler Concurrency Locks (Issue #1559)

We’re seeing a spike in reports regarding thread starvation in the Scheduler component under high concurrency. This issue thread does a solid breakdown of where the lock contention happens, useful for optimizing your queue depth before hitting a wall.

Rate Limiter Stalls: Debugging State Persistence (Issue #1560)

Users are hitting a bottleneck with the rate limiter refusing to reset after transient network errors. Issue #1560 captures the frustration perfectly; if you’re scraping or polling, check the timing logic here or your requests will brick themselves.
