0.102.16

0.102.16 — Plugin-store review compliance

Housekeeping release: changes to satisfy Obsidian's automated community-plugin review.
No behavior changes — same features as 0.102.12, just cleaner under the hood. Still
alpha; keep backups.

Under the hood

• Zip handling switched from JSZip to fflate. .zip / .tar.gz / .stash
  export and import, plus encrypted-bundle handling, now use the dependency-free
  fflate library. This removes legacy polyfill code the review flagged and trims the
  bundle. Bundles round-trip identically (text, attachments, and nested paths
  verified); existing .stash files still import.
• Code-quality cleanups for the store guidelines: OS detection via Obsidian's
  Platform API, inline styles moved to setCssStyles, settings headings use the
  standard Setting().setHeading(), cached note bodies are re-hydrated without
  innerHTML, and unused imports removed. No visible change.

CSS

• Internal stylesheet tidy-up (a mislabeled grid gap), with the remaining intentional
  rules documented. No visual change.
