📄 Description

Summary

This PR implements power management to prevent the system from sleeping during inference operations.

Changes

  • Added server/power_saver.go with AcquirePowerLock() and ReleasePowerLock() functions
  • Uses caffeinate on macOS to prevent idle sleep
  • Uses systemd-inhibit on Linux to prevent idle sleep
  • Integrated power locking into GenerateHandler and ChatHandler

Motivation

Fixes issue #4072: Ollama should prevent sleep when working on heavy inference tasks.

Testing

The implementation uses reference counting to handle concurrent inference requests - power is saved until all inference requests complete.

Fixes #4072
