core.telemetry

Megatron-LM telemetry helpers.

When nemo-lens is installed, the real implementations are used. Otherwise, no-op fallbacks from fallbacks keep everything working.

Submodules: fallbacks — No-op stubs matching the nemo.lens API. span_groups — SpanGroup / MegatronSpanGroup constants and presets. training_metrics — OTel metric recording for the training loop.
