Adds Safari-specific detection and initialization logic to better support audio and video playback, especially for cases where metadata is not loaded as expected. Implements fallback event listeners, user interaction triggers, and exposes an initialization helper to ensure the editor works reliably on Safari and iOS devices.
Implemented keyboard shortcuts for play/pause (Space), jump backward (ArrowLeft), and jump forward (ArrowRight) in the chapters editor. Shortcuts are disabled when typing in input fields to prevent interference with text entry.
When a segment's chapter title is a default generated name (e.g., 'Chapter 1'), the editing field now displays an empty string to trigger the placeholder, improving the user experience for custom title entry.
Introduces a helper function to assign chapter titles like 'Chapter 1', 'Chapter 2', etc., based on the chronological position of each segment. Updates all segment creation and splitting logic in TimelineControls and useVideoChapters to use this naming convention for improved clarity and consistency.
Adjusted the tooltip position transition endpoint for better placement. Updated the chapter input to use a textarea selector, set fixed height constraints, and improved focus and placeholder styles for consistency. CSS and static assets updated to reflect these changes.
