render the Claude pane natively from the transcript (T-137)

The Phase-1 wedge of epic T-132 (D-75): the Claude pane no longer
renders the PTY's TUI. It runs claude in tmux as before (so the
transcript is written) but displays the conversation as native cards
read from the transcript via TranscriptReader — user / assistant
markdown / thinking / tool-use / tool-result. The whole list sits under
a new no-Material ClideSelectionArea (SelectableRegion-based, since
Flutter's SelectionArea is Material and D-7 bans it), so text selects
and copies across cards — recovering the terminal's one real advantage.

ClaudePane drops its Terminal model and the resize-driven spawn trigger
(spawn now fires once on didChangeDependencies with a fixed tmux size,
since the TUI isn't shown); pane.output is no longer consumed. The
terminal builtin is untouched and still available as a general tool.
Input/composer is the next ticket (T-138).
