📄 Description

This PR implements system sleep prevention on macOS during active inference tasks. It introduces a new server/internal/power package that uses IOKit to assert a kIOPMAssertionTypeNoIdleSleep when the scheduler has active requests. This fixes #4072 by ensuring long-running model loads or generations are not interrupted by system sleep.
