Devlog 29: URL Hash Sync, LocalStorage Persistence & Universal Share Event

URL & State Persistence

• Integrated URL Hash (#year,month,...) and localStorage synchronization into time-progress.js to preserve users’ toggle preferences across reloads and shares.
• Added a hashchange event listener to ensure UI check states dynamically update when users use browser navigation (Back/Forward).

Centralized Layout Share Event

• Refactored the #share-menu-btn event listener into BaseLayout.astro, eliminating duplicate share logic across individual tool pages.
• Leveraged document.title dynamically to provide clean, contextual titles for native Web Share API and clipboard copy fallbacks.
