Class anira::Semaphore#

class Semaphore#
Thin semaphore wrapper that mirrors the std::semaphore interface.
Backed either by std::binary_semaphore (modern platforms) or moodycamel::LightweightSemaphore (older Apple deployment targets), selected at compile time. Call sites use a single uniform API regardless of backend.
