Brennan Benson c460de6089 fix(codex): widen the stale-pane sweep retry ladder past the Windows worst case (#10853)
Live Windows 11 validation of #10770 measured store-visible PTY bind -> notice
raised at 3,959 / 4,064 / 5,140 ms across three runs. The ladder delays are
CUMULATIVE (queueNextRung -> queue -> Date.now() + delayMs), so the old
[300, 1500, 4000] fired at 300ms / 1.8s / 5.8s from bind — leaving the worst run
roughly 660ms of margin against the final rung. A slightly slower machine, more
panes, or a colder daemon exhausts the ladder and the card NEVER appears,
silently reintroducing the bug #10770 exists to fix. macOS by comparison
resolved in ~0.66s with most of the ladder unused.

Widened to [300, 1500, 4000, 10_000, 20_000] — cumulative 300ms / 1.8s / 5.8s /
15.8s / 35.8s. Early rungs untouched so macOS still resolves under a second; the
tail clears the Windows worst case by 2.7x and 6.2x. Still bounded at five
attempts, not interval-based; queue/takeDuePtyIds are unchanged so per-PTY rung
independence does not regress, and the notified/dismissed/closed-pane guards
were verified to stop late rungs.

Failure mode if the ladder is still short is "no card" — never a dead keyboard.

Review verified the cumulative arithmetic by measurement rather than reading
(both the author and I initially misread the delays as absolute-from-bind) and
confirmed boundedness deterministically 10/10. It also hardened the
bounded-ladder test: it previously asserted only "5 inspects within 120s", which
a 6th rung at 200s passed unchanged — the test named for termination did not pin
termination. Now asserts vi.getTimerCount() === 0, mutation-proved.

Not verified: the Windows field numbers behind the 10s/20s sizing have not been
re-measured on Windows with this change.

Known follow-up, out of scope: remote SSH panes can never be reported stale (they
are never written to the pane-account registry) yet still ride all five rungs at
15s RPC timeouts, so this change raises wasted remote RPC from ~45s to ~75s per
pane. The sweep and the switch-time marking should both skip remote panes for a
host-account change.
