add native composer to the Claude pane (T-138)

A no-Material EditableText below the ConversationView. Enter submits, Shift+Enter inserts a newline (a Shortcuts override maps plain Enter to a submit intent; shifted Enter falls through to the default newline). Submitted text goes to Claude over pane.write — the same input verb the terminal pane uses, so D-6 parity holds and there's no Claude-only path. Multi-line input is wrapped in bracketed-paste markers so the embedded newlines submit as a single message instead of a stream of submits. Paste handling is stubbed via an injectable resolver (file/image @path support lands in the next commit); plain-text paste falls through.
