%% @doc Registration module for Liquid Conglomerate morphologies.
%%
%% This module provides functions to register all LC morphologies with
%% the morphology_registry. Call register_all/0 during application startup.
%%
%% == Morphology Hierarchy ==
%%
%% The LC uses three chained LTC networks:
%%
%% L2 (Strategic, tau=100):
%%   - Inputs: Evolution metrics (fitness, stagnation, diversity, etc.)
%%   - Outputs: 4 strategic signals
%%
%% L1 (Tactical, tau=50):
%%   - Inputs: L2's 4 strategic signals
%%   - Outputs: 5 tactical signals
%%
%% L0 (Reactive, tau=10):
%%   - Inputs: L1's 5 tactical signals + emergent metrics (evolvable)
%%   - Outputs: Final hyperparameters (mutation_rate, selection_ratio, etc.)
