docs: document WORKER_ENABLED, WORKER_DOMAINS, and WORKER_MAX_LOAD

[liyishuai]

Summary

• Adds a Worker Pool (EvoMap Network) subsection to the Configuration docs
• Documents the three worker pool environment variables: WORKER_ENABLED, WORKER_DOMAINS, and WORKER_MAX_LOAD
• Includes a usage example showing how to start an evolver as a network worker

Details

WORKER_ENABLED=1 opts a node into the EvoMap worker pool. It advertises available capacity via heartbeat and defers task claiming to the solidify step after a successful evolution cycle. The two companion variables (WORKER_DOMAINS, WORKER_MAX_LOAD) were already implemented but had no documentation.

Pull request overview

This PR addresses false-positive “stagnation” restarts by ensuring the evolver loop writes to evolver_loop.log during idle periods via a success log on routine heartbeats (Fixes #216).

Changes:

• Log a heartbeat success message when sendHeartbeat() completes successfully.
