concerto-gpu

GPU monitoring abstractions for Concerto.

This crate provides the [GpuMonitor] trait, which abstracts over the source of GPU telemetry (NVML, mock, or anything else), and two implementations:

• [MockGpuMonitor] — a configurable in-memory monitor used in all tests and for development without real GPU hardware.
• NvmlMonitor — a real NVML-backed monitor, gated behind the nvml feature and only available on Linux. See the nvml module for platform caveats.

The trait is deliberately minimal: callers drive snapshots from the outside, which keeps the implementation trivially testable and leaves caching/interval policy to higher layers.
