OpenClaw Signals: Deadlock Patches, Traceback Polish, and Backoff Refactors

Bug Fix

Patch: Mutex Thread Pool Deadlock Fix

This patch fixes a deadlock bottleneck in the internal mutex thread pool. If you are running high-concurrency workloads, this is a critical update to prevent your pipeline from seizing up.

Fix: Time-to-live (TTL) Enforcement Regression

A regression broke Time-to-live enforcement during the last refactor; this PR puts it back in place. Deploying without this means potential zombie processes hanging around your cluster.

Refactor: Exponential Backoff Logic Cleanup

Logic rework to ensure retry intervals actually back off exponentially. Stops your system from aggressively spamming a service that is clearly timing out.

Robustness

Feature: Custom Error Wrappers for Better Tracebacks

Adds a custom error wrapper to give you cleaner stack traces instead of cryptic kernel dumps. Better visibility into failures means less time staring at logs and more time writing code.

RFC

RFC: Secure Default Event Filters

A new proposal to lock down event filters by default to stop data leakage. Worth reviewing if you have strict compliance requirements or federated deployments.
