* feat: wake parent agents on child completion

* wip: harden child completion wakeup lifecycle

* fix: close the completion-wakeup static failures

Type the durable-claim store fixture, the continue-envelope test helper,
and the terminal message's task metadata so the wakeup suites compile
against the shapes they actually exercise. Replace `Array.prototype.at`,
which the package target library does not provide.

Capture the prepared child thread in a non-optional local before the
provider callback closes over it, and narrow the trigger envelope itself
on `mode === 'continue'` rather than a separately copied mode, so reading
the continue target is sound. Lift the parent-message fallback out of a
nested ternary into a named resolver.

* test: cover the active-predecessor admission fence

The Redis job-creation call gained a thirteenth scalar argument, so the
spec helper reconstructed the HSET pairs one slot early and rebuilt an
invalid job hash; three creation tests failed on that alone.

Give the fence itself direct coverage in both store adapters, which it
had none of despite deciding whether an automatic continuation may
replace a live parent turn. Each proves a running and a requires_action
predecessor are refused with the state a controller needs for a finite
409, that an absent or settled predecessor is admitted, and that an
ordinary user turn without the policy still replaces its predecessor.
The Redis case also asserts a refused continuation leaves the parent's
durable job and chunks untouched.
