Let Tab write a suggestion and open the list on typing, not on caret moves - #22

…ret moves, and drop the unread answer-line flag - Tab in the search box writes the highlighted word of the suggestion list, the same as Enter, and keeps the keyboard in the box, so sta Tab Tab gives status:running. With the example questions open, with no list, and outside the box Tab walks on as before, and Shift+Tab never writes. - The list follows typing: a caret moving through unchanged text (arrows, a click, Home, End) closes it instead of opening a one-row list. Down still asks for it anywhere. A row just written is followed as typing, so the values after a field still open at once. - The sentence under the list names Tab for a list of words and not for the questions. - Says.AnswerLineShown and its flag had no reader since the search message moved into the field, and went with their test and mutation entries.

- Line 98: Update the Shortcut.CompleteWord mapping in Wanted to return
TakeSuggestion only when Suggesting.TabWrites is true and no text composition is
active. Track composition start, updates, and completion with
TextCompositionManager, and prevent OnPreviewKeyDown from accepting the
suggestion until composition ends.
In `@src/Bws.Gui/ViewModels/Says.cs`:
- Around line 147-149: Preserve the public AnswerLineShown API on Says with a
getter that has a defined replacement contract, and retain its property-change
notification behavior if applicable; otherwise, explicitly version and handle
its removal as a breaking API change.
In `@tests/Bws.Gui.Tests/KeyboardTests.cs`:
- Line 341: Update Tab_twice_writes_a_field_and_then_its_first_value to dispatch
Tab through MainWindow.OnPreviewKeyDown with the window focused, rather than
calling Wanted and Act directly; assert the resulting text and focus after the
routed key handling.

Preserve or explicitly version the AnswerLineShown API.
Says is public, and the merge-base code exposed public bool AnswerLineShown. The PR removes it and its notification. No current repository binding uses it, but external consumers can fail to compile. Retain a compatibility getter with a defined replacement contract, or document and handle this breaking API change explicitly.

Test Tab through the routed key handler.
Tab_twice_writes_a_field_and_then_its_first_value calls Wanted and Act directly. It does not exercise MainWindow.OnPreviewKeyDown. Add a focused-window test that dispatches Tab through the routed handler and checks the resulting text and focus.

Review of PR 22. Tab and Enter wrote the chosen row whenever the list was open, so with an input method composing a character in the box a row could be written over text not yet committed. The list now answers CanTake - open, and no composition in progress - and the window hears the start and the end of every text composition in the box, handled or not. The keyboard leaving the box ends a composition, so one abandoned without an end cannot keep the keys from writing. Not measured with a real input method: there is none on the machine this was built on. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
