This change: * Truncates thread names if more than 15 chars with `snprintf`. * Adds warnings for truncated thread names if `-DTRUNCATED_THREAD_NAME_LOGS=ON`. * Add a static assert for string literals to stop compiling if > 15 chars. * Shortens `Resource::Manager` to `Resource::Mngr` to fix the static assert failure. * Updates `CurrentThreadName_test` unit test specifically for Linux to verify truncation.
