3c6f53406b Fix: stop the direction page hanging forever after a re-roll (#469) (#530)
* Fix: stop the direction page hanging forever after a re-roll (#469)

The re-roll leg of the decision-page protocol was documented only in
serve-question.mjs's own header, so agents never ran --update and the
open tab polled a round that could never arrive. Compounding failure
modes: the page poll swallowed every error, the daemon's --timeout was
an absolute guillotine that killed the server under a still-open tab,
a choice posted to a dead server confirmed nothing, and refresh or
Reload on an unresolved round resurrected heartbeats that held the
daemon alive indefinitely.

- new-work.md documents the re-roll leg: rerun concept-seed with
  --from/--reroll, deliver with --update on the same key, never --start
  a second server.
- The page poll terminates and says why: eight consecutive fetch
  failures means the server is gone; the delivery deadline (the
  server's own --idle-grace, inlined into the page) passing means the
  hand never arrived. Both stop heartbeating.
- The daemon's --timeout bounds only the wait for a page to open; once
  the page heartbeats, the server lives while the page does and exits
  after --idle-grace (default 600s) without a beat, including under
  --timeout 0.
- Build this and Re-roll against a dead server fail loudly instead of
  silently swallowing the click.
- The server tracks the window between a collected re-roll answer and
  the --update that replaces the round, and serves the page in waiting
  mode there, so a native refresh re-enters the same bounded wait
  instead of resurrecting dead cards; the in-page Reload button only
  revives a delivered hand.
- --update is exempt from the headless gate and its liveness probe
  trusts a fresh heartbeat over a failed kill probe (sandbox EPERM is
  not death).

Squash of the six review-round commits on this branch, rebased onto
main after the decision-page revamp.

* Fix review findings: persist the replacement deadline, refuse unloadable hands

A browser-native refresh of the waiting page re-entered the bounded wait
with a fresh delivery deadline and an immediate heartbeat, so refreshing
before each deadline expired could hold the daemon alive and keep --wait
on WAITING indefinitely. The server now records when the re-roll or
followup answer was collected, each served waiting page inherits only
what remains of that one allowance, and a page served after the deadline
renders stalled immediately and never starts its heartbeat.

And a next hand the round could not load used to reload-loop the tab:
GET /'s catch kept the file on disk, so /next-status stayed ready:true
forever. --update now refuses a payload without a non-empty options
array at the sender, and GET / discards an unloadable next file so the
bounded wait resumes.

* Fix review finding: a stalled page recovers a late hand without a click

The stall silenced heartbeats so the idle grace could reclaim the
daemon, but that silence read as a closed tab: after a late --update,
--wait saw the stale beat and reported PAGE CLOSED while the user sat
on the Reload screen, so the agent abandoned the browser path the
recovery UI exists for. The stall screen now keeps a beat-free
/next-status watch that reloads into a delivered hand on its own
(GET never beats, so an abandoned flow is still reclaimed), and --wait
no longer concludes closure from a stale beat while an undelivered
next hand sits on disk.

* Fix review finding: a delivered hand must not mask a closed page

The mid-delivery suppression keyed on the next file existing, but a
closed tab never claims that file, so an unconsumed delivery held
--wait on WAITING indefinitely instead of reporting the closed flow.
The suppression is now age-bound: a stalled page's watch reclaims a
delivered hand within seconds, so a file still unclaimed after a 10s
grace means no page is coming back and the stale beat reads as the
closed page it is.

* Fix review finding: stamp the delivery clock at --update, not the copy

--wait's mid-delivery grace reads the next file's mtime, but
copyFileSync's timestamp behavior is the platform's business: a copy
that preserves the source payload's older mtime would start the grace
already spent and report PAGE CLOSED under a live stalled tab. --update
now touches the delivered file itself, so delivery time is delivery
time everywhere.

* Fix review findings: disable canon during the wait, validate --timeout

The waiting and stall screens disabled only the re-roll buttons; the
footer canon action stayed clickable, and a canon pick posted after
--wait had consumed the re-roll could never be collected: it overwrote
the answer, marked the table closed, and exited the daemon under the
agent. Both disable sites now take the canon exit down with the re-roll
buttons; a delivered hand reloads the page and serves it live again.

And --timeout reached the lifetime timer unvalidated: NaN or a negative
value disarmed the no-page exit and the daemon leaked. It now takes the
default unless the value is a finite non-negative number, keeping 0 as
the explicit wait-forever.

* Fix review finding: a second click must not renew the delivery deadline

dealAgain left the re-roll and canon controls live through the answer
POST and the 700ms fly-out, so a second click posted another re-roll
and the server restamped awaitingNextSince, renewing the deadline this
PR made non-renewable on refresh and on the stall screen. The controls
now go quiet at the click itself, in dealAgain and in answer(), and the
server stamps the allowance only on the transition into the wait, so a
duplicate answer racing the disable keeps the first stamp.

Regression coverage on both sides: the unit deadline test posts a
duplicate re-roll mid-allowance and asserts the budget shrank instead
of resetting, and the e2e stall test asserts both controls are disabled
immediately after the click, before the fly-out.

* Fix review finding: a late delivery must survive its claim window

--update could land a replacement hand after the stalled page went
silent but moments before the daemon's idle deadline: the daemon exited
before the page's 1.5s watch could claim the hand, orphaning a delivery
--update had confirmed, and the next --wait reported a server failure.
The idle exit now defers while an unclaimed next hand is younger than
the claim grace --wait already reads (extracted as one shared
constant), so the page's watch deals it and heartbeats resume; a file
unclaimed past the grace still ends the daemon, bounded as before.

Regression test: deliver at idle-deadline-minus-a-beat, assert the
daemon survives past the deadline and serves the late hand.

* Fix review finding: the claim itself must hold the daemon

The idle-exit hold read only the next file's freshness, but GET /
deletes that file when it serves the claimed round, before the
reloading page can post its first heartbeat: a lifetime tick in that
gap saw no pending hand and a stale beat, and exited under the hand
just claimed. GET / now stamps the claim when it consumes a pending
hand, and the idle exit honors the same bounded grace from that stamp,
so the reloading page gets its seconds to beat while an abandoned claim
still ends the daemon at the grace.

The claim-window regression test now also fetches after the claim, past
another lifetime tick, and asserts the daemon survived the gap;
verified it fails on the previous commit.

* Fix review finding: --wait must ride out the claim gap too

The claim deletes the next file --wait's mid-delivery grace watches,
and the reloading page has not beat yet, so --wait in that gap read the
stale beat as PAGE CLOSED while the daemon was alive serving the dealt
round, and the agent abandoned a browser session that had just
recovered. GET / now persists the claim stamp into the per-key state
file, and --wait's suppression honors it under the same bounded grace:
a fresh claim stays WAITING, a claim nobody followed with a beat still
reads as the closed page it is.

Regression test drives --wait through the gap (claim with a stale beat:
WAITING, not exit 4) and past it (backdated claim stamp: exit 4);
verified it fails on the previous commit.
