OpenClaw Signals: Signal Housekeeping, Bus Debugging, and Build Noise Cuts

Code

PR #330: Signal Handler Housekeeping

This PR cleans up signal handling, reducing complexity and potential race conditions. A direct hit on stability for anyone running long-lived agent sessions.

Discussion

Issue #1559: Bus Debugging Proposals

A structured proposal for better debugging on the internal bus. This is where the real work gets done, moving from 'it broke' to 'here's why' with actionable traces.

Issue #1560: Bus State Visibility

Follows up on debugging with a focus on state visibility. If you can't see what the bus is doing, you can't reason about your system. Essential for complex agent choreography.

PR #328: Build Output Noise Reduction

Reduces noisy, non-actionable output during builds. Less noise means faster signal for devs, which directly translates to faster iteration cycles.
