0.2.0

Added

• Auto-update system — check for and install new versions directly from inside KOReader
  via Folder Lock → Check for updates
  • Fetches latest release metadata from GitHub Releases API
  • Downloads release zip and verifies SHA-256 checksum before touching the live plugin
  • Safe swap with rollback: renames live plugin → .bak, extracts new version in its
    place, restores .bak on any failure
  • Startup recovery: cleans up stale .bak after a successful boot, restores .bak if
    the live plugin is missing
  • Override URL for testing with a local dummy server
• Runtime version source — folderlock_version.lua embedded at package time so the
  updater knows what's installed
• Checksum sidecar in releases — .sha256 file published alongside each release zip

Changed

• scripts/package_release.sh now injects the release version into the packaged plugin and
  generates the .sha256 checksum file

Assets

• folderlock.koplugin-0.2.0.zip — plugin archive
• folderlock.koplugin-0.2.0.zip.sha256 — SHA-256 checksum (verified automatically during
  in-app update)
