AX Principle 2: comments must show concrete usage, not restate the
function name. "New creates a new Logger with the given configuration"
restated the signature — replaced with a callable example.

Abbreviated names `globalMu` and `sb` require a comment to understand
their purpose, violating AX Principle 1 (Predictable Names Over Short
Names). Renamed `globalMu` to `globalMutex` and `sb` to `builder`
throughout logger.go.

Create pkg/logging with:
- Log levels: Debug, Info, Warn, Error
- Structured fields support (key-value pairs)
- Component-based logging (WithComponent)
- Global logger convenience functions
- ParseLevel for configuration
- Full test coverage
The package provides a migration path from log.Printf to
structured logging without external dependencies.
Example usage:
logging.Info("miner started", logging.Fields{"name": minerName})
logger := logging.New(cfg).WithComponent("Manager")
logger.Warn("connection lost", logging.Fields{"pool": pool})
