Release v1.9.9999

v1.9.9999

Fixes

• Stop false-positive same-page deletions in annotation sync — highlights sharing a page could be wrongly marked deleted; the scan now uses fine-grained position ranges instead of page numbers.
  (#87)
• Eliminate O(n²) scan in annotation sync — syncing books with hundreds of annotations could take up to ~20 minutes; the scan is now linear. (#69)

Features

• Make plugin menu location configurable, with a new Menu location settings submenu.
• Add user-defined directory exclude list for automatic progress sync (manual push/pull unaffected).

Other

• Test suite hardening (real XPointers in bookmark deletion tests, flushed nested sync schedules in integration tests) — no user-facing changes.
