0.99.0

• New manatools.aui module that re-exports backend-agnostic UI classes (enums, YWidget, YTreeItem, YTableItem, YTableHeader, YItem, events and exceptions) from yui_common for easier migration from libyui-style code.
• Unified YUI frontend with automatic backend detection (Qt / GTK / NCurses) and convenience accessors: YUI.ui(), YUI.widgetFactory(), YUI.app().
• Improved backend selection strategy and safer imports for Qt/GTK/curses backends (deferred probing and clear warnings when fallbacks are used).
• BaseDialog (manatools.ui.basedialog) enhanced with a robust _setupUI layout pattern and guidance to protect column minimum widths using MinSize + Frame + ReplacePoint (fixes flicker/resize issues).
• AppConfig (YAML-based) for system and per-user configuration file management, with userPreferences/systemSettings accessors.
• EventManager improvements for consistent widget/menu/timeout/cancel event handling.
• Various API stabilizations: re-exported enums (YUIDimension, YEventReason, YCheckBoxState, ...) and helper globals for backward compatibility.
• Improved common dialogs and helpers: AboutDialog, warningMsgBox, infoMsgBox, msgBox, askOkCancel, and askYesOrNo with a unified, backend-agnostic API for simple informational and question dialogs used by applications.
