Description:

The download resume feature fails due to two bugs: (1) Early exit check returns when file exists, preventing resume logic from executing for partial downloads, and (2) httpx stream re-entry crash occurs when attempting to restart download for complete files, causing "stream has been closed" error.
Fix: Remove early exit check and add proper file completeness detection using Content-Length comparison before triggering retry logic.

Acceptance Criteria:

[ ] Partial downloads resume correctly after interruption
[ ] Complete files are detected and skipped without crash
[ ] No regression in normal download functionality
