feat: simplify worker spawning logic and update macOS build workflow

Updates the release workflow to run macOS builds inside a Docker container with explicit registry authentication and adjusted artifact paths. Bumps the obikmer crate version to 1.1.29 and adds *.log to .gitignore. Simplifies NUMA worker spawning by lowering the activation threshold from 0.95 to 0.2, replacing complex stateful tracking with a direct efficiency check, and downgrading progress logging to debug level. Includes general code formatting improvements for readability.
