雷电芽衣 4512df79e6 fix(tui): terminal escapes ride the writer queue and teardown is bounded
A terminal that stopped draining the pty parked the writer thread inside
its tty write while it held the stderr lock; the next inline stderr write
from the event loop (mouse toggle, notification, kitty clear) deadlocked
the loop, and /quit hung on the unbounded writer join and the teardown
writes.

EscapeWriter queues out-of-band escapes on the frame writer: the mouse
capture toggle, notifications (title, progress, protocol), the auth
cursor, gboom keyboard flags, the wrap clipboard request, and the kitty
clears (queued per agent view and merged into the frame's post-flush,
nested subagent views included). The $EDITOR/$PAGER handoff aborts when
the writer does not drain. WriterThread::join_within and the teardown
run under a 2 s grace; after a stall fd 2 is silenced, the exit hints,
relaunch and update prints are skipped, and the panic hook keeps only its
log report.

Ported from upstream 1.0.19 (grok-build EscapeWriter, WriterJoin,
run_bounded_teardown), extended to the remaining inline writes.

Key Concepts

  • AppView — owns the welcome screen, agent sessions, and global config
  • AgentView — one per session; owns the prompt, scrollback, tool panes, and modals
  • PromptWidget — text editor component with file search (@), slash commands (/), history search, and paste elements
  • Action/Effect — Elm-style architecture: input → Action → dispatch → Effect → state update
