chore: bump version to v0.3.11

feat: implement pixel-perfect custom rendering for block elements, powerline and box drawing
- Render block elements (U+2580-U+259F), box drawing lines, and powerline characters using precise GPUI vector paths instead of fonts. - Snap logical coordinates to exact physical pixels using window.scale_factor() to perfectly eliminate SDF anti-aliasing gaps and bleeding. - Fixes visual seams in terminal UI layouts.

 This project focuses on providing a high-performance and visually appealing shell workspace by combining local and remote environments with a rich set of built-in features. 

+## 🚀 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.
+

+全新发布的 v0.3 迎来了架构和体验的全面升级：
+- ✨ **全局实时字体设置与字号调节**（感谢 [@ancion](https://github.com/ancion) 提供的 [PR #6](https://github.com/rust-kotlin/ashell/pull/6)）：支持自定义全局 UI 字体和终端渲染字体，支持实时字号调节并自动记忆。
+- ✨ **SFTP 多任务并发传输队列**：引入全新的独立传输对话框，支持多文件并发上传下载，提供精准的进度展示。
+- ✨ **持久化工作区记忆**：您对侧边栏的尺寸拖拽、终端主题、字体、隐藏文件开关等一切设置都会在下次启动时原样恢复！
+- ✨ **智能断线重连与状态感知**：全面增强的 SSH 网络异常处理机制，断线后直接提供美观的覆盖层用于一键重连或关闭。
+- ✨ **多语言热切换增强**：深度优化的 i18n 系统，包含中文与英文在内的所有界面文案现在均支持热切换。
+- ✨ **智能右键快捷操作**：新增终端右键智能复制与粘贴功能，提供专属设置项自由控制开关，并支持根据不同操作系统自适应显示原生快捷键提示。

Author	SHA1	Message	Date
TomZz	c3201e7c30	chore: bump version to v0.3.11	2026-06-15 01:14:48 +08:00
TomZz	2d5062ed75	feat: implement pixel-perfect custom rendering for block elements, powerline and box drawing - Render block elements (U+2580-U+259F), box drawing lines, and powerline characters using precise GPUI vector paths instead of fonts. - Snap logical coordinates to exact physical pixels using window.scale_factor() to perfectly eliminate SDF anti-aliasing gaps and bleeding. - Fixes visual seams in terminal UI layouts.	2026-06-15 01:14:42 +08:00
TomZz	d7d6faeeb1	feat: optimize transfer history dialog UI and logic - Add an independent scrollbar track to prevent it from overlapping with the content list - Add a "Clear History" button with text label, placed seamlessly next to the close button in the custom header - Implement a 100-record limit for transfer history and display this limit in the header - Persist the cleared transfer history into the session config immediately after clearing - Disable default dialog close button and reconstruct header to avoid state update collision and panic Resolves #25	2026-06-14 23:58:46 +08:00
TomZz	19a4274473	feat: enhance UI for active tabs and settings dialog - Active Tab: Now uses `FontWeight::BOLD`, `text_base()` font size, and the primary theme color. This makes it far more distinct from inactive tabs, especially in themes where background differences are subtle. - Settings Dialog: Overrode the default sidebar style to use the main dialog background (`cx.theme().background`), seamlessly blending the sidebar with the content pane. - Refactor: Renamed unused `_cx` parameter to `cx` in the settings dialog render closure since it is now being utilized to access the theme.	2026-06-14 23:34:01 +08:00
TomZz	4bb3bee6c8	fix: ensure selection background fully covers wide characters (#24 ) Rationale: Previously, the terminal renderer generated background highlight rectangles (`LayoutRect`) with a hardcoded width of 1 cell (`cells: 1`) for every character. For full-width CJK characters (which carry the `Flags::WIDE_CHAR` flag and visually span 2 columns), this caused the selection and custom background colors to render across only half of the character's visual width. This fix correctly interprets the terminal cell flags during layout generation: if a cell possesses `Flags::WIDE_CHAR`, it generates a background rectangle spanning 2 cells (`cells: 2`). As a result, the highlight now matches the exact bounds that the text occupies in the terminal grid, cleanly fixing the partial highlighting of Chinese text.	2026-06-14 23:19:33 +08:00

TomZz	8a535fad5a	fix: fallback to ssh-rsa signature for legacy OpenWrt dropbear Resolves issue #20 where RSA 4096-bit keys failed to authenticate on OpenWrt Dropbear servers. The previous logic exclusively tried rsa-sha2-512 and rsa-sha2-256, which caused authentication aborts on servers only supporting legacy ssh-rsa (SHA-1) signatures. - Modified `private_key_with_alg` to `private_keys_with_algs` to return a list of supported algorithms including SHA-1 fallback for RSA keys. - Implemented an iterative algorithm fallback loop in both SSH and SFTP connection authentication phases.	2026-06-14 14:22:24 +08:00

TomZz	33a3d624b7	Refactor: integrate comprehensive tracing logs and SSH multiplexing This commit introduces a robust logging system and optimizes remote metric collection over SSH: - Logging Infrastructure: - Replaced ad-hoc `eprintln!` and `println!` with the `tracing` crate. - Implemented a rolling file appender in `~/.config/ashell/log/` keeping the last 6 minutes of logs. - Restricted stdout logging to debug builds only, keeping release builds clean. - SSH Multiplexing & Performance: - Shared `russh::client::Handle` across tasks using `Arc<Mutex<>>`. - Replaced the 5-second polling of new SSH connections with `SampleMetrics` over the existing channel. - Eliminated authentication log spam and vastly improved polling latency. - Optimized terminal `resize` events to only trigger when dimensions actually change, further reducing UI layout spam and backend load. - Application & Network Auditing: - Log window lifecycles (open, close). - Log UI actions such as session connects and tab closures. - Detailed connection logs distinguishing between graceful EOFs, network drops, and abrupt closures. - Granular SFTP tracking including directory navigation, creation, batch uploads/downloads, and online file editing.	2026-06-14 13:57:50 +08:00

TomZz	4ba3000538	feat: add customizable system monitoring position - Add settings to position the system monitoring panel at the Bottom, Sidebar, or Hidden. - Support dynamically reallocating UI space when the monitor panel is moved. - Implement a simplified, compact card-style system monitoring view for the sidebar (similar to v0.3.5 design). - Add full localization for monitoring setting and sidebar metrics.	2026-06-13 03:34:29 +08:00
TomZz	e7e2c67393	fix: restore body_panels layout sizes on app startup - Ensure the size of the monitoring panel (the second child of body_panels) is explicitly loaded from configuration rather than falling back to the hardcoded default of 328px.	2026-06-13 03:01:40 +08:00
TomZz	47b03510b2	feat: optimize monitoring card layout for memory and disks - Hide swap memory progress bar entirely if total swap is 0. - Add temporary overlay scrollbar for the disk list using ScrollbarShow::Scrolling, allowing users to scroll through long disk lists without displaying a persistent scrollbar UI. - Fix unused variable and dead code cargo warnings.	2026-06-13 02:56:11 +08:00
TomZz	54c50c871a	feat: fix SFTP monitoring panel minimize behavior and layout - Isolated the monitoring panel from ResizableState when minimized to prevent the GPUI flex layout and proportional resize engine from forcing it out of the window bounds. - Wrapped the terminal's resizable container with flex_1 to constrain it to available space, preventing the fixed-height 114px panel from overflowing the bottom of the screen. - Saved the user's dragged panel size (prev_monitoring_size) immediately before minimizing. Double-Frame Delay Update Reason: When expanding the panel from 1 child back to 2 children, ResizableState needs one full render frame to recognize the child count change, append the new panel, and initialize its zero-size defaults. If we update the sizes synchronously on the first frame, ResizableState would overwrite our manual sizes during its layout initialization. Waiting for a double-frame delay guarantees that ResizableState has fully populated the second panel in its internal state, allowing us to accurately restore the user's previously dragged height without being overridden by the layout engine.	2026-06-13 02:42:04 +08:00
