feat: mobile response viewer — read full Claude responses via native scroll
Claude Code's Ink framework uses alternate screen buffer + VPA cursor positioning, resulting in near-zero xterm.js scrollback on mobile. Instead of fighting terminal scrollback, this adds a native scrollable overlay that reads structured responses from Claude's JSONL transcripts. - New API: GET /api/sessions/:id/last-response reads transcript JSONL - ?context=full returns full conversation thread (user + assistant) - Fallback to terminal buffer with ANSI stripping if no transcript - Response viewer panel: bottom sheet with native iOS/Android scroll - "More" button loads full conversation context as threaded view - Eye icon in header bar (mobile only), no toolbar space impact
