Subject: [PATCH] [core] Inline HighFrequencyLoopRequester::is_high_frequency()

Move is_high_frequency() from out-of-line definition in helpers.cpp
to inline in the header. This allows the compiler to inline the
trivial check (num_requests > 0) at the call site in
Application::loop(), avoiding a function call every loop iteration.
