Survey the three realistic ways to surface a claude-code session
inside the dashboard TUI:
1. Handoff — drop curses, foreground claude, restore on exit
(the existing `e`/`p` pattern, extended). Minimal code,
side-by-time rather than side-by-side.
2. Embedded emulator — own a PTY, parse claude-code's ANSI
stream via `pyte`, paint it into a curses pane. Real
"pane in the dashboard" but a six-week build with one new
dep and several integration trap-doors (alt-screen, resize,
input routing, multi-PTY state).
3. External multiplexer — delegate pane creation to tmux /
iTerm / wezterm when detected. Tiny code, but splits the
operator's mental model and gives up layout control.
Recommendation: ship Option 1 first; defer Option 2 to "only if
Option 1 is observably insufficient"; treat Option 3 as a
niche augmentation for power users.
Calls out four followups worth verifying before committing
(PTY behavior at small sizes, attach-to-existing-exec, SIGWINCH
handling, `-it` vs `-i` for the embedded path).
