Fixes deadlock/hanging and log corruption when logs are written asynchronously while an interactive task is rendering. It avoids deadlock by allowing direct stream writes when isPending() is true, and introduces pendingBuffer to correctly aggregate, render, and flush partial terminal lines.


PR created automatically by Jules for task 10899409696913749581 started by @Mopsgamer

This commit addresses the issue where asynchronous logging during active
tasks caused deadlocks or terminal output corruption.

1. Bypassed mutex acquisition in `Logger.print` if there are pending
   tasks. This allows direct writes to the stream, which are safely
   intercepted by our hook, avoiding deadlock with the render loop.
2. Implemented `pendingBuffer` in `hook.ts` to buffer incomplete log
   lines and avoid breaking terminal layout during active task displays.
3. Updated `render.ts` to prepend buffered incomplete lines to the
   interactive task list and flush on termination/cleanup.
4. Added unit tests for deadlock prevention and partial line buffering.
