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})

- Collect stats from multiple miners concurrently using goroutines
- Minimize lock duration by taking a snapshot of miners early
- Remove redundant existence check (snapshot is sufficient)
- Extract collectSingleMinerStats for cleaner code
- Add early return when no miners are present
This reduces overall stats collection time when multiple miners
are running, as API calls now happen in parallel instead of
sequentially.

Previously, StopMiner would fail if the miner was already stopped
(crashed or killed externally), leaving it stuck in the workers list.
Now the miner is always removed from the manager, even if Stop()
returns "miner is not running". This allows cleaning up dead workers.
