Jordan Ritter 62474be1dd fix(showcase/ci): make a cancelled build slot a first-class outcome
`job.status` for a matrix slot is success|failure|cancelled, but the
per-slot writer laundered cancelled into `skipped` before publishing its
result, so a slot killed by `timeout-minutes` became indistinguishable
from one that legitimately never built.

That erased the only signal that could tell a partially-cancelled fleet
build from a clean one. GitHub's status functions cannot recover it:
`cancelled()` is documented as "returns true if the workflow was
canceled" (workflow-scoped, and FALSE for a leg-only cancel), and a
cancelled ancestor is not a FAILED ancestor so `failure()` is false too.

Add `cancelled` to the BuildOutcome contract, add `cancelledSet()`, and
have the aggregator publish `any_cancelled` + `cancelled_services`
alongside `any_success`. `successSet` still excludes cancelled slots, so
the redeploy intersection is unchanged — a slot that pushed no image
still cannot enter the redeploy CSV.
