Multi-window: - Per-window ImGui contexts (fixes input, scroll, and rendering isolation) - Per-instance scroll and mouse state in ImGuiRenderer (no more statics) - Proper GL context activation during window destruction - ValidateBufferIndex guards against stale curbuf_ across shared buffers - Editor methods (CurrentBuffer, SwitchTo, CloseBuffer, etc.) use Buffers() accessor to respect shared buffer lists - New windows open with an untitled buffer - Scratch buffer reuse works in secondary windows - CMD-w on macOS closes only the focused window - Deferred new-window creation to avoid mid-frame ImGui context corruption Swap file cleanup: - SaveAs prompt handler now calls ResetJournal - cmd_save_and_quit now calls ResetJournal - Editor::Reset detaches all buffers before clearing - Tests for save-and-quit and editor-reset swap cleanup Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
