InstinctaZero Android v0.8.11 — Reliable saves & faster editing

Faster repertoire editing and reliable large-board saves, without changing the simple design.

• Fixed a confirmed restore bug that kept only the first 512 moves across a notation tree. Removed the silent 256 KiB board-save rejection; saves now commit transactionally, with a visible retry if storage fails.
• Repertoire additions no longer rebuild the imported book and its comments. A real-library extension measured about 20 ms instead of 800 ms in native desktop tests; lookup remained fast. These are not phone latency measurements.
• Large notation navigation updates in place instead of redrawing/serializing the entire tree. Mainline navigation, privacy, portrait orientation, comments, personal edits and Undo are preserved.
• Original board storage is backed up locally before migration. Existing repertoire PC backups remain compatible. Already-overwritten board branches are not guaranteed recoverable.

Install over your existing app; do not uninstall or clear its storage. No repertoire redownload, pairing change or PC restart is needed. Local PGNs and archived games are not modified.

Verified with native Android tests, isolated real-library refresh/restart/Undo/restore comparisons, separate-process board persistence, and phone-sized touch previews. The USB-tether phone was not used for testing.
