/**
 * A text input component for composing messages.
 *
 * This component provides a rich text input experience with automatic resizing,
 * keyboard shortcuts, file paste support, and intelligent focus management.
 * It integrates with the composer context to manage message state and submission.
 *
 * When rendered inside `Unstable_TriggerPopoverRoot` and a popover is open, the
 * underlying `<textarea>` automatically receives `aria-controls`,
 * `aria-expanded`, `aria-haspopup`, and `aria-activedescendant` for the
 * combobox relationship. These computed attributes override user-provided
 * values for those four ARIA props while the popover is open.
 *
 * @example
 * ```tsx
 * // Ctrl/Cmd+Enter to submit (plain Enter inserts newline)
 * <ComposerPrimitive.Input
 *   placeholder="Type your message..."
 *   submitMode="ctrlEnter"
 * />
 *
 * // Old API (deprecated, still supported)
 * <ComposerPrimitive.Input
 *   placeholder="Type your message..."
 *   submitOnEnter={true}
 * />
 * ```
