Test Details Overview

Report preconfigured peer connect failures (#5092)

* Report preconfigured peer connect failures

Propagate outbound TCP connection outcomes through reachout callbacks, including local rejection errors.

Log failed attempts to explicitly configured peers and cover callback success and failure paths in tcp listener tests.

* Replace the nullable `connect_callback` default (`{}`) with no-op lambda default

Allowing call sites to invoke the callback
unconditionally and removing all `if (callback)` guards.

* Add `nano::noop<F>()` helper; replace inline no-op lambdas

Replace repeated inline no-op lambda defaults with a reusable
`nano::noop<F>()` utility that constructs a type-erased no-op
callable for any `std::function<void(Args...)>` specialization.
