- Introduced the Softsign activation function to the activations module. - Updated ActivationType enum to include Softsign. - Enhanced ActivationConfig to support Softsign with an alpha parameter. - Implemented the ActivationSoftsign class for applying the Softsign function. - Added unit tests for Softsign, covering core functionality, initialization, and JSON configuration parsing. - Updated run_tests.cpp to include tests for Softsign functionality.
