f361cdfaca [ContentCacheManager] deeply integrate the HashFileTracker

- Let the tracker be authoritative for already written ranges
  This is saving a stat call per newly written range.

The previous regex could mistake user provided pdf files, like
 `fake_output.pdf`, as the final output file.
The frontend expects to find a `output.pdf` file on success.
