Fix PDF decompression, add proper noun detection toggle, bump to 0.9.25

- document-scanner.js: Add missing await on _inflateSync() call — FlateDecode
  streams were not being decompressed because the async function was called
  without await, causing decompressed to hold a Promise instead of data
- content.js, storage.js, options.html, options.js: Gate proper noun / capital
  letter detection behind a new detectProperNouns setting (default off); was
  previously always-on causing noisy false-positive warnings on AI thinking
  output and common capitalized words
- Bump version 0.9.23 → 0.9.25
