调研方向
先阅读 docs/superpowers/specs/2026-08-02-clowder-m9-agent-survival-design.md §M9c，然后检查 crates/clowder-daemon/src/pane.rs 以及 #52 中的 Screen::snapshot() substrate。在实现之前定义 PTY-host 和 fd-passing 协议。当 agent、其进程、scrollback 和 companion shells 能够在 daemon 被 kill 并重新启动后无需 respawn 仍然存活时，即表示完成。

描述
Context
Agent survival shipped in two slices this cycle:
- M9a (#50) — durable
agents.jsonregistry, reconcile-on-startup, adapter session-resume (claude --continue). Agents re-spawn in their worktree after a daemon restart. - M9b (#51) — full split-layout restore (companion shells rebuilt in the same arrangement).
M9c is the deferred capstone: true zero-disruption survival. Today a restart re-spawns each agent (fresh process; the prior conversation is only recovered via the adapter's own resume, and scrollback/companion output is lost). M9c makes agents — and their scrollback and running processes — survive a daemon restart with no re-spawn at all.
Design (already written)
docs/superpowers/specs/2026-08-02-clowder-m9-agent-survival-design.md §M9c (DEFERRED — design only):
A persistent PTY-host process owns the agent PTYs + child processes + recent backlog and outlives the daemon. The daemon becomes a client of it: on restart the daemon re-attaches to the still-running agents (PTY master fds handed over via
SCM_RIGHTSfd-passing over a unix socket), so agents — and their scrollback — survive with zero disruption.
This splits today's daemon into a small, rarely-restarted PTY-server + the churny restartable control-daemon.
Scope (big — its own spec → plan → SDD cycle)
- New PTY-host component + an fd-passing protocol (
SCM_RIGHTSover a unix socket). - Backlog/scrollback ownership moves to the host (the daemon's current in-memory backlog becomes the host's).
- Child reaping in the host (not the daemon).
- Suppress the current triple-kill on the daemon side (SIGHUP-on-master-drop +
Drop for Pane+shutdown()explicit kill — seecrates/clowder-daemon/src/pane.rs), so agents aren't killed when the daemon exits. Screen::snapshot()(from the VT-grid milestone, #52) is a ready substrate for the recent-screen restore.
Acceptance
A running agent survives a daemon kill + relaunch with its process, scrollback, and companion shells intact — no re-spawn, no lost conversation — and the app reconnects to the still-live session.
