QuickPIM++ v2.17.0 - Reliable multi-device sync

Browser Sync consistency

Added validated atomic snapshot generations so partially delivered, corrupt, stale, or unsupported cloud data is never applied.
Added field-aware reconciliation for preferences, enabled tabs, aliases, favorites, saved reasons, bundles, activity, and per-installation usage counters.
Preserved concurrent edits from multiple computers without double-counting activity or silently restoring deleted values.
Delayed generation acknowledgement until cloud read-back, allowing competing last-writer updates to reconcile on the next pass.
Accounted for the browser sync service's real JSON storage usage and retained complete local categories when a bounded cloud snapshot must be truncated.

Split cloud purge and resume state into independent monotonic markers, rejected stale snapshot epochs, and prevented older installations from recreating purged data.
Retired stale installation records while preserving active device names and source attribution.
Coalesced duplicate background synchronization, retried transient sync delivery errors, and kept Settings usable when the browser sync service is temporarily unavailable.
Canonicalized role identifiers across aliases, favorites, usage, activity, restored selections, and request fingerprints.
Hardened request recovery, token refresh coordination, partial Azure scope results, timestamps, and bounded imported or synchronized collections.

467 automated unit and integration tests passed.
Type checking, production build, eight browser UI checks, Microsoft Edge compatibility, and Edge sideload smoke passed.
Dependency audit reported zero known vulnerabilities.
Chrome Web Store and Microsoft Edge Add-ons received the same verified Chromium package.
