* fix(opencode): prevent late aborts from canceling replacement turns
OpenCode aborts are session-scoped, so provider idle alone does not make a session safe to reuse. Keep abort retries owned by the stopping turn and require both abort settlement and provider idle before dispatching the next runner operation.
* fix(opencode): retain the stop barrier through provider idle
Keep the stopping operation authoritative until both its session-scoped abort and provider-idle evidence settle, including stale idle-session interrupts. Also keep the real drift fixture credential-allowlisted and wait for command output pipes to drain.

The run boundary had grown into a mutable flag bag plus a raw-event
buffer that was replayed and re-classified after the fact. Each new
interleaving needed another predicate, and the classification kept
losing autonomous wakes.
Restore stopping as a turn-state variant that owns exactly two things:
the session-scoped abort it issued (with its single owned retry) and the
canceled run's terminal. Runner operations wait on both; a failed abort
fails closed. Provider status reconciliation now ends the stop through
the same transition an SSE terminal takes.
The canceled run's residue is suppressed only up to that terminal.
Events published afterwards are a new run by construction and take the
normal live path, so a wake no longer waits for abort settlement and
cannot be dropped by a retention heuristic.
* fix(opencode): emit cancellation before adopting the next run
The acknowledgement ran off a promise combinator, so a wake adopted from
the event right after the terminal could reach subscribers before the
canceled turn's turn_canceled. Acknowledge synchronously from whichever
proof lands first instead.
* docs(opencode): attach the stop doc comment to its interface
* fix(opencode): retry the stop in progress instead of opening a second
Pressing Stop again after an abort failed built a detached boundary: its
fresh abort could succeed while the canceled turn kept waiting for an
acknowledgement, so the daemon sat out the full cancel timeout before
force-canceling. A repeated Stop now replaces the abort owned by the
stop already in progress, which is what carries the acknowledgement and
what lifts the fail-closed gate.
* fix(opencode): accumulate every abort a stop has issued
A repeated Stop replaced the stop's abort settlement instead of adding
to it, so a first request still in flight — the slow-teardown case the
cancel cap exists for — no longer held the gate. The replacement could
start while that request was live and get cancelled by it, which is the
race this boundary exists to close. Reuse now waits for every abort the
stop issued, while only the newest can hold the gate closed.
* fix(opencode): scope abort settlement to the session, not the stop
Abort is session-scoped, so its settlement has to be too. Tracking it on
the stop meant a new stop boundary silently dropped an older request
that was still in flight, and that request could still cancel whatever
run started next. The session now accumulates every abort it has issued;
the stop is left owning only the run it is stopping.
* fix(opencode): recheck the abort gate after waiting on it
A waiting prompt read the settlement once, so a Stop issued while it
waited was invisible to it: the older abort would settle, the prompt
would start, and the newer one could still cancel it. Drain until the
settlement observed is the current one.
