OpenClaw Signals: Agent Resource Yields, Bus Latency Cuts, and Ephemeral Panic Fixes

Fix

Agent Process Cleanup Overhaul Lands in #330

This patch hardens agent restart logic so previously allocated resources don't turn into silent leaks. It's a major stability win for long-running orchestration where you can't afford the zombie processes.

Architecture

Structural DBus Dependency Removal in #328

Refactoring the IPC layer off DBus means we're looking at tighter latency for internal requests. If you're running high-frequency command loops, this structural shift is worth tracking closely.

Bugfix

Crash Path Override for Containers

The panic logic previously relied on default path assumptions that failed in ephemeral container environments. This fix ensures logs actually land where you tell them to, even when standard streams degrade.
