Refactor the Instant type to be generic over a ClockSource type parameter, enabling static enforcement of clock correctness across APIs that deal with time. Previously, the clock source was implicitly fixed (typically CLOCK_MONOTONIC), and developers had to ensure compatibility manually. This design eliminates runtime mismatches between clock sources, and enables stronger type-level guarantees throughout the timer subsystem.
