fix: UI/UX improvements for tabs, sidebar layout, and scrolling

- Redesign TabBar: remove bottom border and adjust height to a compact 40px.
- Fix UI auto-scrolling: TabBar, Open Session dialog, and Saved Sessions sidebar now accurately scroll selected items into view.
- Fix layout bounds for scrollbars so they render continuously and always stay visible.
- Pin sidebar headers (logo, stats) to the top while only the session list scrolls.

+## 🚀 v0.3 Massive Update!
+
+The brand-new v0.3 introduces comprehensive upgrades to both architecture and user experience:
+- ✨ **Global Real-Time Font Settings** (Thanks to [@ancion](https://github.com/ancion) for [PR #6](https://github.com/rust-kotlin/ashell/pull/6)): Customize your global UI fonts and terminal rendering fonts independently. Adjust text size in real-time with automatic persistence.
+- ✨ **Concurrent SFTP Transfers**: A dedicated Transfers dialog now supports highly optimized, concurrent file uploads and downloads with precise progress display.
+- ✨ **Persistent Workspace State**: Your sidebar width adjustments, terminal themes, font settings, and file visibility preferences are completely restored upon your next launch!
+- ✨ **Intelligent SSH Disconnect/Reconnect**: Greatly enhanced SSH connection resilience. Provides a beautiful and localized overlay for one-click re-connection on unexpected disconnections.
+- ✨ **Hot-Swappable i18n System**: Deeply optimized internationalization. Switch instantly between English and Simplified Chinese without restarting the application.
+- ✨ **Smart Right-Click Actions**: Added intelligent right-click copy and paste for the terminal, featuring a dedicated settings toggle and OS-native keyboard shortcut hints.
