Fix duplicate (1) filenames after app restart with partial downloads

Browse Source 
When the app restarts (or updates) while downloads are in progress,
partial files remain on disk but reservedTargetPaths (in-memory) is empty.
claimTargetPath treated the unclaimed-but-existing file as a conflict and
appended (1) to the filename, breaking RAR split archive extraction.

Fix: if a file exists on disk but no other item has reserved the path,
allow overwriting instead of creating a duplicate.
