Replace the effect-log tests' global util/log module mock with local spies on Log.create so the logger compatibility tests no longer leak into unrelated unit suites. Keep the coverage for routing, annotations, spans, and cause formatting while allowing the full package test workflow to run cleanly.
Add a small Effect logger bridge that routes Effect logs through the existing util/log backend so Effect-native services can adopt structured logging without changing the app's current file and stderr logging setup. Preserve level mapping and forward annotations, spans, and causes into the legacy logger metadata.
