Add configurable clipboard suggestions with a default timeout of 30 seconds. Keep already-visible suggestions pasteable after expiry so the target does not disappear just as the user tries to paste; include a dismiss button and Chinese translations.

Fix integer stepper overflow when the timeout has a lower bound of -1 and no explicit upper bound.

Validated with an arm64 simulator build and code signing, format/lint checks, all three CTest suites, and two Appium integer configuration tests.

Summary by CodeRabbit

• New Features
  • Clipboard text can now appear as a suggestion in the keyboard toolbar, where you can paste or dismiss it.
  • Configure clipboard suggestions and their timeout. A timeout of −1 keeps suggestions from expiring.
  • Integer settings now provide clearer accessibility values and respect their minimum and maximum limits.
• Bug Fixes
  • Clipboard suggestions are hidden when the keyboard closes, and blank clipboard entries are not shown.

Walkthrough

The pull request adds configurable clipboard suggestions, suggestion-state handling, and toolbar controls to dismiss or paste suggestion text. It also updates integer steppers to enforce optional bounds and adds coverage for suggestion behavior and integer settings.

Changes: Clipboard Suggestions

Layer / File(s)	Summary
Suggestion settings and integer bounds iosfrontend/iosfrontend.h, common/runtime-api.h, common/runtime_keyboard.cpp, src/config/IntegerView.swift, appium/test_integer.py, po/zh_CN.po	The iOS clipboard configuration adds suggestion visibility and timeout settings, and runtime getters expose them. Integer steppers handle bounded and unbounded values. The Appium test checks the timeout lower bound and history-limit behavior.
Suggestion state and behavior tests common/ClipboardSuggestion.swift, common/CMakeLists.txt, tests/backup/CMakeLists.txt, tests/backup/ClipboardTests.swift	ClipboardSuggestionState captures text, evaluates timeout, and provides hide, dismiss, and take operations. Clipboard tests exercise these behaviors, including zero history retention.
Keyboard capture and suggestion controls uipanel/VirtualKeyboard.swift, uipanel/Toolbar.swift, keyboard/KeyboardViewController.swift	The view model connects clipboard captures and settings to suggestion state. The toolbar displays suggestion dismissal and paste controls, and the keyboard hides the suggestion when it disappears.

Merge Risk: Low · up to 401f1

Replacing copied text with an image can leave the old text in the suggestion toolbar. Dismiss that suggestion on non-text clipboard changes; the remaining risk is bounded.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Dismiss the suggestion when a changed pasteboard has no text.

When the pasteboard changes to non-text content, recordCurrentPasteboardContents() returns without dismissing the current suggestion. The old text can remain visible and pasteable until dismissal or keyboard disappearance.

Suggested fix

-    guard let text = pasteboard.string else { return }
+    guard let text = pasteboard.string else {
+      vm.dismissClipboardSuggestion()
+      return
+    }

Expose dismissClipboardSuggestion() to KeyboardViewController if its current access level prevents this call.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Prevent expired suggestions from reappearing.

If a capture expires under the current timeout, refresh() hides it but retains capturedText. A later configure(timeout: -1) changes the timeout before reevaluation and presents that expired text again. Discard expired captures before applying a longer timeout. Keep an already visible suggestion pasteable until reevaluation. (raw.githubusercontent.com)
