Defined in: src/tracing/RecordingTracer.ts:77
Cap on the in-memory recording, oldest evicted first.
Unset means unbounded, which is right for a test that asserts over
every span but wrong for anything long-lived: a tracer left enabled
on a busy system grows without limit. Set 0 to keep none at all —
the sensible choice when onSpanEnd is the real sink and
recorded() is never read.
