Detailed Description

Tiny chrono-based timer used by the CA module Examples.

This header is intentionally minimal: it lives in the public headers layout so the Examples can include it the same way as the rest of the library, but it is not part of the engine API. It is only used by the Phase-5 microbenchmarks that need a deterministic wall-clock reading (e.g. Examples/ca_bench_example.cc).

Public surface:

• Bench_Timer — start/stop wall-clock timer.
• bench_seconds(F) — measure the wall time of one invocation.
• format_throughput — pretty-print "M cells / s" numbers.

Everything is inline and depends only on <chrono> and <cstdio>, so it does not pull anything else from Aleph-w into the Examples build graph.
