#reflect_tracing
Tracing and metrics split into sibling libraries: reflect_telemetry for aggregates over time, reflect_tracing for spans at microsecond resolution. The engine is Maciek Gajewski's 2021 Wro.cpp technique — thread-local ring buffers, ~200 ns per span, function address as payload, DWARF resolution at dump time. Reflection contributes the instrumentation layer, which today is one explicit scope-guard line per function and tomorrow (C++29, P3294/P3157) becomes a pure annotation.
