This commit applies a detailed physiological model to all remaining simple organ classes, bringing them to a level of complexity consistent with the Heart, Lungs, and Brain. Updates include: - Esophagus: Simulates peristalsis and bolus movement. - Stomach: Implements a gastric state machine for digestion. - Intestines: Adds segments (duodenum, jejunum, etc.) and simulates absorption. - Pancreas: Differentiates endocrine and exocrine functions. - Gallbladder: Simulates storing, concentrating, and releasing bile. - Kidneys: Models nephrons, GFR, and electrolyte balance. - Bladder: Implements a micturition cycle with pressure dynamics. - Spleen: Models red and white pulp for blood filtering and immunity.
