PKHeX-Avalonia

Use when adding a new generation-specific save-data editor (a "Misc Editor"-style dialog scoped to one SAV<N> type, e.g. coins/BP/flags/records) to PKHeX-Avalonia — scaffolds the View, ViewModel, ViewLocator entry, open-command, and menu wiring across the Clean Architecture layers.

Use before opening a pull request in PKHeX-Avalonia, or when asked to check a branch/diff is PR-ready — verifies UIVersion was bumped correctly, no PKHeX.Core edits snuck in, and upstream UI changes have frontend-parity coverage.

Use when a "PKHeX.Core Sync Required" issue is open (the daily auto-generated sync-labeled issue) and PKHeX.Core must be brought 1:1 with upstream kwsch/PKHeX, propagated to the Avalonia layer, version-bumped, and shipped as a merged PR. Keywords - PKHeX.Core sync, upstream sync, kwsch/PKHeX, last-synced-sha, UIVersion bump.
