Detailed Description

RAII helper that sets the thread-local replay flag for its scope, restoring the previous value on destruction.

Nests correctly: a replay() call that itself triggers another replay() (not a pattern this framework uses today, but not precluded) leaves the flag true for the whole nested extent and restores the outer call's value on the inner guard's destruction – the same nesting behavior session::detail::ScopedContext already has for Context.
