l0ng-ai ebec6096d6 fix(windows): make the install directory actually replaceable before updating
The updater stopped the daemon and started the Inno installer the moment
the daemon's endpoint disappeared — but the endpoint going away is not
the same event as the images being released. The ConPTY hosts
(OpenConsole.exe) are the daemon's children, not the shells', so the
per-pane kill never reached them, and the daemon's exit(0) skipped every
destructor that would have closed them; they kept the installed
OpenConsole.exe open for seconds after --stop-daemon returned. Silent
Setup then hit the lock, took the suppressed dialog's default (Abort),
and the updater's recovery relaunched the old build — "updated,
restarted, still the old version". A daemon that died without cleaning
up made it permanent: its orphaned hosts survive indefinitely, which is
the DeleteFile-code-5 users hit even after "closing everything".

Reproduced both shapes in isolation before fixing: with a pane open,
--stop-daemon returned ~1s in while OpenConsole.exe stayed locked for
another ~1.4s; after taskkill on the daemon, the orphaned host held the
lock forever.

The shutdown now finishes what it starts, at every layer that can be
the last one standing:

  * The daemon reaps its remaining descendants and waits for them
    before exiting, while the endpoint — the signal stop() watches —
    is still up.
  * stop() reads the pidfile before asking, and waits for that process
    to actually exit after the endpoint goes, not just stop listening.
  * The recorded-daemon reap waits for the images to be released
    instead of returning on the async TerminateProcess.
  * stop_for_update(dir) — reached via --stop-daemon
    --update-install-dir, which PrepareToInstall and the portable
    updater now pass — also terminates anything still running from the
    installation directory (the orphan case no pidfile can name) and
    only returns once the .exe/.dll images there open for writing,
    naming the holdouts in the error if they never do.
  * The updater runs that clearing itself before invoking Setup, so a
    directory that cannot be cleared fails with a cause in update.log
    and relaunches the previous build, instead of Inno's bare
    "DeleteFile failed; code 5".

The update dialog on Windows also told a macOS truth — "the background
service keeps running, so whatever is open in your panes survives".
Windows cannot replace a running daemon's image, so its install path
stops the service; the dialog now says so.

Why

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Editor-grade input — suggestions, completion, highlighting, history search
  • Remote development — files, repos, panes, and git data stay on the remote machine
  • Native SSH — profiles, SFTP, port forwarding, and jump hosts
  • Agent-aware — Claude Code, Codex & co.: status, notifications, git context
  • CLI + Skills — agents create panes, run commands, and inspect output
