/**
 * Bind form element value to state with two-way data binding.
 *
 * @remarks
 * Updates the element value when state changes, and updates state
 * when the user modifies the element. Handles different input types:
 * - text/textarea: binds to value, uses input event
 * - checkbox: binds to checked, uses change event
 * - radio: binds to checked, uses change event
 * - select: binds to value, uses change event
 * - number: binds to value (as number), uses input event
 *
 * @example
 * ```html
 * <input g-model="name">
 * <input type="checkbox" g-model="isActive">
 * <select g-model="selectedOption">
 * <textarea g-model="description"></textarea>
 * ```
