focus the Claude composer on a background tap

T-227. A tap on empty conversation area now lands the cursor in the
composer. The conversation area is wrapped in a translucent
GestureDetector whose onTap focuses a pane-owned composer FocusNode, so
message links, copy buttons, and the SelectableRegion's selection drags
keep winning their own gestures — only an unclaimed tap reaches us. It's
a no-op while a prompt holds the interaction zone (D-78), so a tap never
pulls focus over an open prompt.

The composer learned to accept an external focus node (the pane owns it,
so it survives composer remounts) and attaches its key handling to
whichever node it's given.

4. Selection/caret position preserved, not just the string (nice-to-have).
Implementation sketch: store the draft (text + selection) on the per-session model/controller (kernel- or session-scoped), not in the composer widget''s State.

- Up: if the caret isn''t on the first visual line, move up one line (normal editing); once on the first line, Up steps to the previous prompt in history. Down mirrors it (move down within multiline; at the last line, step to the next/newer entry).
- When entering history, stash the current draft as the newest entry so Down past the most recent restores exactly what the user was typing.
- History is the sequence of prompts submitted from this composer (this session at least; persisting across restarts is a nice-to-have).
- Plays well with the existing Enter-submit / Shift+Enter-newline and the slash typeahead (Up/Down already drive the typeahead when it''s open — history nav only applies when the typeahead is closed).
Implementation: a small history controller + caret-line detection in ClaudeComposer (EditableText); the Up/Down handling lives alongside the existing _onKey/Shortcuts.

Today focusing the composer requires precisely clicking the field; a click on the conversation background does nothing, so the input is fiddly to focus.
Goal: make the composer easy to focus — a click on dead space in the pane lands the cursor in the input, like clicking an empty area of a chat app focuses its reply box.
Acceptance:
1. A tap on non-interactive Claude-pane background focuses the composer input (cursor ready to type).
2. Taps on actual controls keep their behavior (copy, approve/reject, AskUserQuestion choices, tab strip, links) — the focus-grab must not swallow or pre-empt their gestures.
3. Text selection in the transcript still works: a click-drag to select must NOT steal focus to the composer (only a plain tap/click-release with no selection focuses it).
4. Interaction-zone nuance (D-78): when a permission / AskUserQuestion prompt has replaced the composer in the interaction zone, a background click should focus that prompt''s primary control instead of the (absent) composer — or do nothing — never resurrect the composer.
Implementation sketch: wrap the pane body in a tap recognizer (behavior: translucent / deferToChild) that, on a tap that did not hit a child gesture and produced no text selection, requests focus on the composer FocusNode.
