* fix(wsl-host): boot only the focused WSL host, and keep a stopped one down
E9 connect policy, part 1. A stopped distro now boots only for an explicit user action
or when its host becomes focused:
- Visible work is the active workspace plus workspaces focused earlier in this window
that still have tabs. Saved tabs alone no longer count, so a launch with two hosts
boots only the focused one.
- After a confirmed stop (wsl --shutdown, WSL update) the host is parked. Liveness no
longer reboots it even when it is visible, and polls get "<distro> was stopped"
instead of a boot. Re-focusing the host, Connect, or the distro running again lifts it.
- Liveness recovery always needs a confirmed-running distro, so a distro that stops
mid-recovery is never booted again.

* test(wsl-host): launch boots one of two hosts; polls never boot; lost contact never parks

* fix(wsl-host): only a focus entry or a user action boots a WSL host (E9 review)
Review of #33838:
- Re-focus never lifted a park: a host focused earlier stayed in the visible set, and
the renderer skips unchanged reports. The renderer now sends a separate focus entry
(focusHost) each time the user switches to a workspace on a WSL host, including the
launch restore; only that, or Connect, lifts a park and may boot.
- Runtime calls could boot: ensureForRuntimeCall connected any visible, unparked host.
It now reads the host's reachability first: a confirmed-stopped distro parks at once,
an unreadable running list refuses, and only a distro confirmed running is
reconnected (for visible work). Visible work itself never connects anything.
- Turning WSL hosts on no longer boots every visible host, and focus isn't recorded
while they're off; the window re-reports its focused host instead.
- Each window's visible work is kept apart and unioned, so one window can't drop
another's.
- wakeForAutomation/isConnected move to the automation PR, which uses them.

* fix(wsl-host): a poll waits for liveness's verdict right after an exit (E9 re-review)
Right after `wsl --shutdown` WSL can still list the stopping distro as running (the
supervisor waits and re-reads for exactly this). A poll's cold probe then read
'unreachable', reconnected, superseded the pending distro-stopped verdict and booted
the distro again. The supervisor now reports when it is settling (a verdict in
progress, or a watch/holder exit within the last few seconds), and a runtime call
refuses instead of reconnecting then; the verdict parks the host as before.
