📝 WalkthroughWalkthroughRegex-constrained options now expose validity state in native and QML editors. Invalid values receive visual feedback and block dialog or page saves. The KCM validates all pages before persisting configuration. Build targets now require and link the Fcitx5 configuration library. ChangesRegex validation and guarded configuration saves
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds regex-constrained option editing, but invalid existing list entries and nested values can still be accepted during save in several UI paths. This can persist configurations that violate their declared constraints, so merge should wait for validation and save-propagation fixes. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Validate every existing regex-constrained list item before an outer save.
The current guards validate only an active add or edit editor. They do not validate entries already loaded into the list model. An invalid value saved by an earlier version or an external editor can therefore pass a later page or dialog save.

Add aggregate validation for nested ConfigWidget dialogs.
When optionWidget is null, the handler accepts invalid nested values without checking ConfigWidget. Expose aggregate validity and check it before calling dialog->accept().
