A [group] node may now declare EVENT trigger templates (kv/docs/files/
pubsub) that bind a group-owned handler. cron/queue/email stay app-only
(rejected on a group at both the manifest and the reconcile layer).
- Trigger is now owner-polymorphic (app_id: Option, group_id: Option),
mirroring Script's Phase-4 reshape; TriggerRow carries group_id
(#[sqlx(default)] so interactive RETURNING clauses still hydrate).
- insert_trigger_tx takes a ScriptOwner (App XOR Group) and writes the
group_id column; the queue advisory-lock branch is app-only.
- TriggerRepo::list_for_group loads a group's templates; load_current's
Group arm uses it so the diff is NoOp on re-apply and prune-able.
- apply_service reconcile drops the "triggers are app-only" assumption;
validate_bundle_for rejects non-event kinds on a group. The semantic-
identity diff is already per-owner.
- CLI manifest allows event-kind [[triggers]] on [group], rejects
cron/queue/email there.
Templates don't fire yet — the live dispatch union lands in T3. All
trigger/apply/manifest unit tests green; clippy -D clean.
