feat(ui): render the chat pane as a Rich transcript (AppUI)#7
Merged
Conversation
Add AppUI, the RuntimeUI implementation that routes content into the full-screen pane. It holds a list of Rich renderables as the transcript source of truth and renders them to a single ANSI string at the live terminal width, caching the result until the content or width changes — so a resize re-wraps cleanly and streaming stays cheap to invalidate. The pane control in app.py becomes a FormattedTextControl over ANSI(ui.render), with wrap_lines off because Rich already wraps at the shared width. build_app gains an optional ui seam so the worker (a later branch) can inject and drive the same AppUI. Content methods mirror the terminal UI exactly, preserving every display guard: secret redaction and workspace-relative path resolution in the tool-call summary, and control/ANSI sanitization at every sink — the model-response sink included, matching ResponseStream. Approvals raise until the focus-swap lands; the thinking indicator and post-turn stats stay no-ops for now. DESIGN.md section 31.12 covers the pane render and the AppUI seam.
