feat(ui): ctrl-o expands the live streaming card to full tail (#335, #337)#359
Conversation
…337) Pain point @dacec354 raised twice: while the model writes a long plan or todo list, the streaming card only shows the last 4 lines, so the content scrolls past before you can read it. And once a long reply settles, you may want to fold it back down — but `<Static>` already flushed the bytes to scrollback so that half can't be unwound. This collapses both requests into one keystroke: `ctrl-o` toggles "expanded" mode on the live streaming card. Expanded shows the last 60 visual lines (capped so the card can't swallow the whole viewport) plus a `⋯ N earlier lines above` hint when content overflows. Collapses back to the 4-line preview. Auto-resets to collapsed at the end of every turn so each new reply starts compact. The same `(LIVE)` constraint covers #337's fold-toggle ask: only not-yet-committed cards are addressable. Settled cards live in Ink's `<Static>` which writes terminal scrollback once, no take-backs. The `expanded ⌃o` / `preview ⌃o` pill in the card header advertises the keybind so users discover it without reading docs.

Summary
@dacec354 raised two related asks:
spacecan pause it #337 (second half) — wants a shortcut to fold the last message.Single keystroke covers both:
ctrl-otoggles "expanded" mode on the live streaming card.⋯ N earlier lines abovehint when it overflows.expanded ⌃o/preview ⌃opill in the card header advertises the keybind.The fold-toggle half of #337 is solved by the same mechanism (you can fold long content back to 4 lines while it's still live). Settled cards live in Ink's
<Static>which already wrote the bytes to terminal scrollback — no take-backs there. The pre-existingspacepause for the undo banner (PR #356) was the first half of #337; together they close it.The first half of #337 (
spacepauses 5s undo) shipped in PR #356. This PR closes both #335 and #337 by addressing the remaining ask.Test plan
