AtomChat

v0.2.4

新增

• 防刷屏：同一发送者连续发送完全相同的内容时合并为一条消息，名字旁显示 xN 次数；开关在设置 → 聊天。
• 紧凑消息分组：同一发送者 5 分钟内的连续消息只保留第一条的头像与名字，后续气泡间距收紧（Discord/Telegram 式）；开关在设置 → 聊天，默认关闭。
• 跨消息文字拖选：文字选择不再限制在单条消息内，可跨多条消息拖选，Ctrl+C 一次复制多段。
• 历史保留天数：设置 → 聊天可精确输入保留天数（0 = 永久，1–365 天），到期历史文件在进世界时自动清理；输入框支持 Enter 提交、Esc 取消、点击其他区域自动提交。
• 数据目录治理与图片缓存压缩：自动下载的聊天图片缓存与 companion 他人头像数据从 config/atomchat/ 迁到 <游戏目录>/atomchat-data/；聊天图片磁盘缓存改为 768px WebP/PNG 压缩缓存，启动和写入时自动清理旧文件（上限 500 文件 / 100 MB），旧版迁移遗留目录自动删除；「关于」页新增「清除图片缓存」卡片（带二次确认），显示当前缓存占用。
• 设置页可折叠分组与左对齐粗体组标题：所有设置子页的现有分区标题可折叠；组标题改为左对齐粗体并带细分隔线。

更改

• 历史保留天数由滑条改为右侧输入框：避免滑条无法精确停在 1、3 等小数值；输入框常驻显示，点击即编辑。
• 紧凑消息分组默认关闭。
• 恢复原版 bundled 字体：撤回 MiSans/Inter 实验，避免部分中文文本粗细不一。

修复

• 打开聊天屏崩溃：紧凑分组在计算最后一条消息的下一行间距时越界（IndexOutOfBoundsException）；边界探针现在在消息列表末尾直接返回 false。
• 档案退出动画错乱：详情页互推返回时，pageNavDx 把“返回中”的档案页误判成“新页进入”，方向反/叠层；现按 push/pop 标志决定滑动方向。
• 重复消息计数角标位置与强调色：计数移到气泡外侧垂直居中并跟随界面强调色，不再压住气泡。
• 头像 companion 协议加固：客户端发送前检查通道是否协商，避免向无 companion 的服务器发未知包。
• 历史保留天数输入框问题：修复点击后无光标、点其他区域不失焦、单次按键数字翻倍（1 变 11）等问题。
• 中文文本粗细不一：回退到原 bundled 字体，消除部分字符由 MiSans/Inter 混排造成的字重差异。

Added

• Anti-spam: consecutive identical messages from the same sender merge into one bubble with an xN counter. Toggle in Settings → Chat.
• Compact message groups: within a same-sender five-minute run, only the first message keeps the avatar/name row and later bubbles use a tighter gap. Toggle in Settings → Chat, off by default.
• Cross-message text selection: drag-select text across multiple messages and copy it all with Ctrl+C.
• History retention days: Settings → Chat now lets you type the exact retention count (0 = forever, 1–365 days); expired files are pruned on world join. The field commits on Enter, cancels on Esc, and commits on outside click.
• Data-dir cleanup and compressed image cache: auto-downloaded chat-image caches and companion avatar uploads moved from config/atomchat/ to <gameDir>/atomchat-data/; chat images are cached on disk as 768px WebP/PNG, trimmed at startup and after writes (500 files / 100 MB cap), and old marked migration directories are deleted automatically. About page has a confirm-guarded “Clear image cache” card showing current usage.
• Collapsible settings groups with left-aligned bold headings: every settings sub-page now treats section headings as foldable groups; headings are bold and left-aligned with a divider.

Changed

• Retention control is an exact input field instead of a slider: it sits on the right side of the row and always shows the current value.
• Compact message groups default off.
• Restored the bundled font: the MiSans/Inter experiment was reverted to fix uneven CJK stroke weights.

Fixed

• Crash when opening the chat screen: compact-group lookahead indexed one past the last message; the edge probe now returns false at the end of the list.
• Profile exit animation was reversed/overlapped: detail-to-detail pops used destination-rootness instead of the push/pop flag, so the profile page slid the wrong way.
• Duplicate counter placement/accent: moved beside the bubble, vertically centred, using the accent colour.
• Avatar companion protocol hardening: the client checks negotiated channels before sending requests/uploads.
• Retention input issues: no caret, no blur on outside click, and doubled digits (1 became 11) are fixed.
• Mixed CJK font weights: reverted to the original bundled font.
