P2.3: publish enforces cross-entity identity (no cross-app dangling edge)

Browse Source 
Repo.publish validated entities individually and checked
artifact.release_id == release.id, but never verified the published
aggregate forms one consistent identity graph. It could commit a channel
whose app_id differs from the release's app (a channel of app B pointing
at app A's release) or artifacts whose app_id differs from the release's
app — exactly the dangling/cross-app edge the acceptance forbids.

Add Integrity preconditions to the publish transaction (reusing the
existing len-reset/channel-restore rollback so the model is unchanged on
failure): the release's app must exist, the promoted channel must belong
to that app (chan.app_id == release.app_id), and every artifact must
belong to that app AND name this release (a.app_id == release.app_id and
a.release_id == release.id).

Extend tests/repo_transaction.sx with cross-app channel and cross-app
artifact cases asserting publish raises Integrity and leaves the model
unchanged; the existing rollback and no-dangling assertions stay green.
