The updateTaskField, addUpdatedDate, and updateTaskDescription functions
only matched Unix line endings (\n), causing task updates to silently
fail when files had Windows line endings (\r\n).
Updated all three functions to:
- Match both \r\n and \n line endings in regexes
- Detect and preserve the original line ending style when writing back
This fixes drag & drop status updates in the aggregator web UI.
