feat(learn,app): the field's row as one, its model by name in its provider's colour, the microphone dictating (ADR 0021, D69)

The developer's review of 4 Nov 2026. Below the question, × and + stand
at the start, who answers is centred and the conversations and the
microphone stand at the end, every button the same rounded square, the
microphone listening and Send too. The row above the text ("Only what I
choose · 2 parts") goes, as +'s sheet offers the same choice; a web
search gets + with that row alone. Who answers shows its model's name
alone ('Haiku 4.5', AssistantProvider.modelName: Anthropic's without
"Claude", others as they are), outlined in its provider's colour (D60).
The microphone is halkyon_app's Dictation: what is said goes where the
cursor stands, and it listens again after each pause until stopped. It
gives way to Send once anything could be sent, as Claude's field does.

Whats-New: The question's buttons are in one row: close and + on the left, who answers in the middle, Conversations and the microphone on the right.
Whats-New: What goes along is chosen under +, for the web search too.
Whats-New: Who answers shows the model's name, in its provider's colour.
Whats-New: The microphone keeps listening after a pause, writing where the cursor is, until you stop it.
Whats-New-De: Die Knöpfe der Frage stehen in einer Reihe: Schließen und + links, wer antwortet in der Mitte, Unterhaltungen und Mikrofon rechts.
Whats-New-De: Was mitgeht, wählst du unter +, auch für die Websuche.
Whats-New-De: Wer antwortet, zeigt den Namen des Modells, in der Farbe seines Anbieters.
Whats-New-De: Das Mikrofon hört nach einer Pause weiter zu und schreibt, wo der Cursor steht, bis du es stoppst.

     microphone stays, dictating into the question (D69), so speaking still writes a
     question the person reads before sending. Nothing kept changes: conversations begun
     in voice mode were kept as any other (D48) and read as before.

+  answers is centred, and [history, microphone or Send] stand at the end, each group

+  - **The microphone dictates** (halkyon_app's `Dictation`, Meditate's ADR 0038, D15):
+    what is said goes where the cursor stands, set apart by spaces, and it listens again
+    after each pause until stopped or silent three times running, rather than writing
+    after the text once and stopping. It stands at the end while nothing could be sent,
+    and gives way to Send once something could: a word written, a part chosen or a file
+    attached (as Claude's field does with a file; over showing both, which would need a
+    third button at the end). Where nothing recognises speech, Send stands there alone.
+    A device with no recogniser installed (GrapheneOS) says so, naming two to install,
+    FUTO Voice Input and Google's speech services (`SpeechStart.noRecognizer`), rather
+    than doing nothing.
+  - **Who answers shows its model alone** (`AssistantProvider.modelName`): Anthropic's
+    without the family its models share ("Claude Haiku 4.5" as "Haiku 4.5"), every other
+    provider's as it is ("GPT-5"), and the button is outlined in its provider's colour
+    (D60), which names the provider instead; the web search in the theme's outline. The
+    menu keeps full names under the providers' names.
