v0.20.3 - Fix threading imports in monitor example scripts (2026-06-04)

What Changed?

This release fixes two threading import issues in the monitor example scripts. monitor_events.py was missing the threading import after it was accidentally removed in a previous refactor, causing a NameError at runtime. monitor_thresholds.py had an unused threading import that was removed for clarity.

What's New

Fix: Restore missing threading import in monitor_events.py

What it does: Restores import threading that was accidentally deleted in commit 48760a9 when stdin mode was removed. DirectoryMonitor still uses threading.Lock() to guard _file_positions against concurrent access from the watchdog thread.

How to use it: No changes needed — monitor_events.py will run without NameError again.

Fix: Remove unused threading import from monitor_thresholds.py

What it does: Removes import threading from monitor_thresholds.py where it was never used. ThresholdFileMonitor watches a single file accessed only from the watchdog Observer thread, so no locking is required.
