fix: progress bar tracks files not bytes, retry on 502, dedup folders

- Overall bar progress based on file count (was bytes, causing 50%
  bar at low file count when large files uploaded first)
- Bandwidth computed manually from completed bytes / elapsed time
- Per-file bars show spinner + name only (no misleading 0 B counter)
- S3 upload retries up to 3x on 502/503 with backoff
- Folder dedup: list_children before create, reuse existing folders
- File dedup: skip files already present in target folder
- Connection pooling: reuse DriveClient's HTTP client for S3 PUTs
- Default parallel back to 8 (retries handle transient 502s)
