lifedever/TaskTick v1.8.3 on GitHub

What's Changed

#28 UI freeze with high-output scripts — Running scripts that emit heavy log streams (npm run dev + Spring Boot dual-streaming) no longer pegs the main thread and freezes the UI. Replaced the per-chunk O(N) string concatenation in LiveOutputManager with an O(1) line buffer; pipe I/O is now coalesced at 50ms before crossing to the main thread; the log viewer renders via NSTextView (TextKit fragmented layout) instead of SwiftUI Text, which choked on the 512KB ceiling. Sample shows main-thread time in the live-output pipeline went from 97% → 0%.
"0秒后" stuck in task rows — Task list, Quick Launcher, and log rows no longer freeze on "0秒后" / "in 0 seconds" after a task completes. The relative-time formatter quantizes |diff| < 1s to "0秒后" in zh-Hans, and SwiftUI didn't auto-refresh the row. Added TimelineView and a "just now" / "刚刚" short-circuit; rows now tick every minute.
Log truncation now keeps the suffix instead of prefix — When stdout/stderr exceeds 512KB, the last 256KB is kept (with the stack trace and exit reason) rather than the first 256KB. For build/start scripts this is the part you actually need.

tasktick create CLI command — Create tasks from a script file via the command line:
```
tasktick create "stress test" --script /path/to/script.sh --manual
tasktick create "daily backup" --script ~/scripts/backup.sh --repeat daily --at 08:00
```
Supports --shell, --cwd, --timeout, --manual, --repeat, --at, --no-enable, --json. The GUI owns the SwiftData write — CLI generates the UUID and posts a cli.create notification, then polls the read-only store to confirm.

New IOBatcher (per-task pipe coalescer) and LogTextView (NSTextView wrapper for virtualized rendering).
12 new unit tests covering LineBuffer edge cases (CR / CRLF, amortized trim, pending overflow). All 23 tests pass.

#28 大量日志输出会卡死 UI — 跑日志输出量大的脚本（比如 npm run dev + Spring Boot 同时输出）不再把主线程占满、界面卡死。重写了 LiveOutputManager：用 O(1) 行缓冲替代之前每个 chunk 都做 O(N) 字符串拼接和截断；I/O 在 50ms 窗口内合批后再切到主线程；日志查看器从 SwiftUI Text（500KB 字符串撑不住）换成了 NSTextView（TextKit 分片布局）。采样显示主线程在 live output 链路上的占用 从 97% 降到 0%。
任务列表卡在"0秒后" — 任务列表、Quick Launcher、日志行不再卡死在 "0秒后" 上。系统的相对时间格式化器在中文 short 风格下，会把 |diff| < 1秒 量化成 "0秒后"，而 SwiftUI 任务完成后不会自动重画那一行。加了 TimelineView + "刚刚" 短路逻辑，每分钟自动 tick 一次。
日志截断改为保留末尾而不是开头 — stdout/stderr 超过 512KB 时保留最后 256KB（错误堆栈和退出原因都在那），而不是开头那 256KB。对于编译/启动脚本来说，结尾才是你真正需要的部分。

tasktick create CLI 命令 — 从命令行直接创建任务：
```
tasktick create "stress test" --script /path/to/script.sh --manual
tasktick create "daily backup" --script ~/scripts/backup.sh --repeat daily --at 08:00
```
支持 --shell、--cwd、--timeout、--manual、--repeat、--at、--no-enable、--json。CLI 只生成 UUID 并发送 cli.create 通知，由 GUI 负责实际写入 SwiftData，避免多进程写库竞争。
