feat(openclaw): add workerHost config for Docker deployments

When the OpenClaw gateway runs in Docker and the claude-mem worker runs
on the host, localhost:37777 is unreachable from inside the container.

Add a workerHost config option (default: 127.0.0.1) so users can set it
to host.docker.internal for Docker-based deployments.

Changes:
- Add workerHost to ClaudeMemPluginConfig interface
- Read workerHost from plugin config in plugin entry point
- Update workerBaseUrl to use configurable host
- Add workerHost to openclaw.plugin.json config schema
- Update startup log to show configured host
