/**
 * The component for selecting a single file or multiple files for upload by dialog or drag and drop.
 *
 * ## Event Handling
 * - `onChange`: Called when user selects files through dialog or drag-and-drop
 * - `onClear`: Called when user clicks the clear button (user-initiated only)
 * - `onValueCleared`: Called when controlled value transitions from non-empty to empty (external changes only)
 *
 * ## Controlled vs Uncontrolled
 * - Controlled: Provide `value` prop to control file names externally
 * - Uncontrolled: Use `defaultValue` for initial state, component manages internal state
 *
 * ## Enhanced Features
 * - **Explicit clear button**: Provides discoverable way to clear files
 * - **Controlled/uncontrolled modes**: Proper state management for both patterns
 * - **Provide 'onClear' (user-initiated only)**: Clear the file selection
 * - **Provide 'onValueCleared' (external changes only)**: Called when controlled value transitions from non-empty to empty
 * - **Drag and drop support**: Visual feedback and enhanced file selection UX
 *
 * ## Internationalization
 * This component supports internationalization through text override props following the MFUI Component Internationalization Strategy.
 * All text props are optional with Japanese defaults for backward compatibility.
 *
 * @see {@link https://github.com/moneyforward/mfui/blob/main/docs/ADRs/2025-12-05-component-internationalization-strategy.md | Component Internationalization Strategy ADR}
 *
 * Also extends the props of `<input type="file">` element
 *
 * @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file
