Subject: [PATCH] fix: use task.filePath in aggregator update/archive/delete
 handlers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Task files are named 'task-001 - title.md' not 'task-001.md'.
The handlers were constructing incorrect filenames instead of using
the filePath property stored when tasks are loaded.
