Close #34
Summary by cubic
Makes printf/puts thread-safe under preemptive scheduling by deferring UART writes to a low-priority logger task. This avoids race conditions and prevents other tasks from blocking during output; falls back to direct output when the queue is full.
Written for commit 3359f53. Summary will update automatically on new commits.
