#155 Polish Production Mobile Agent Conversation

[ananmouaz]

Closes #155: a production mobile agent conversation recipe, plus the minimal library hooks it needed.

flutter_ai_elements 0.5.0 (defaults keep existing behavior)

• AiSuggestions(layout: row | list | grid): full-width follow-up rows and a starter grid. The grid drops to one column on narrow screens and at large text sizes. A null onSelected disables the suggestions while a response streams.
• AiConfirmation(status: awaiting | submitting | approved | denied | expired) with localized status lines. Only awaiting shows buttons. The host still executes and persists the decision.
• focusNode on AiComposer/AiPromptInput; keyboardDismissBehavior on AiChat/AiConversationView; sentence capitalization in the composer and question fields.
• AiQuestion shows an answered check. AiMessageBubble no longer leaves gaps for parts a partBuilder hides. AiTask titles wrap at large text sizes.

Demo: demo/lib/production/ (opened from "Production recipe" on the home screen, or run with flutter run -t lib/main_production.dart)

• The flow: ask → progress → answer and sources → follow-up, with empty, loading, failed/retry and settled states.
• A run summary built from tool-call state, never from reasoning. Raw tool details sit behind the "More" menu.
• A source-details sheet, a question that leads to a result card (Add / Edit / Discard), and an approval gate through onToolCalls that expires when the user taps Stop or sends a new message.
• A header based on Mobbin references (page-colored, centered title, circular actions).
• Tests: 8 interaction tests, plus 13 golden checks (light, dark, RTL, large text on a 320 pt phone, reduced motion). The goldens are platform-sensitive, so CI does not run them, like the existing demo capture tests.
• Docs: recipe 13 in docs/recipes.md, with Mobbin attribution that separates what the screenshots show from what we adopted.

Not done: real Android and iOS device checks. AgentDesk has no mobile platforms set up for this project, and the maintainer chose to skip them. The screenshots come from the Flutter test renderer, not from devices. integration_test/screenshots_test.dart now captures recipe frames for a later device run. Streaming raw Markdown is left to #129; Shift+Enter and copy feedback are left to #127.
