Add an Edit action that opens the selected clipboard item in the main app. Save directly to the shared database, or open Sync config after saving to a private store; update the open editor when another item is selected and request keyboard focus again.

Validation: arm64 simulator and OS64 Release builds, format/lint, and all three CTest tests passed. Added coverage for edit URLs, shared/private saves, HTTP retries, and switching an open editor. The final device focus adjustment still needs verification on hardware.

Summary by CodeRabbit

  • New Features
    • Added the ability to edit clipboard items from their context menu. Edits reject blank or duplicate text, and private-mode saves can continue to synchronization.
    • Added support for opening clipboard edits through links.
  • Bug Fixes
    • Improved handling of clipboard edits when items are missing, deleted, or changed elsewhere.
  • Tests
    • Added coverage for editing clipboard items, link handling, and synchronization scenarios.

Walkthrough

Adds a clipboard-edit deep link from the keyboard, a main-app editor, and transactional store updates for shared and private clipboard entries. The flow validates requests and text, preserves entry metadata, and routes changed private-mode saves to synchronization.

Changes: Clipboard Editing

Layer / File(s) Summary
Edit request and store behavior
common/ClipboardEdit.swift, common/CMakeLists.txt, tests/backup/*, docs/synchronization.md
Adds URL parsing and generation for edit requests and transactional store editing. Tests cover validation, metadata preservation, private entries, competing edits, and retry synchronization. The guide documents edit and synchronization behavior.
Keyboard-to-editor flow
uipanel/Clipboard.swift, src/ContentView.swift, src/ClipboardEditView.swift, src/CMakeLists.txt, appium/test_clipboard_edit.py, docs/synchronization.md
Adds the keyboard Edit action, main-app URL routing, editor UI, and post-save navigation to synchronization configuration for private-mode saves. Appium tests check editor text for deep-linked requests.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 42fab

Reopening a changed item may show stale text, and a save completing after another item is selected may close the new editor and lose unsaved input. These should be fixed, but the identified risk is limited to those sequences.

Key the reset task by the full request.

When App receives another valid edit URL with the same UUID but changed text or metadata, the existing ClipboardEditView receives the updated request. Its @State remains unchanged because .task(id:) is keyed only by the UUID. The editor can therefore display and save the previous request’s text.

-    .task(id: request.id) {
+    .task(id: request.url) {

Guard save completion by request instance.

ClipboardEditView.save() calls a parameterless completion after the asynchronous save. If a newer edit request replaces viewModel.clipboardEdit first, the completion clears the newer request and can discard its unsaved editor input. This is incorrect UI behavior, not a crash or service-availability failure. Pass a per-request token, clear only the matching request, and keep private-mode sync navigation outside the guard.
