Brings QueueError / PubsubError / InvokeError in line with sibling
shape used by KvError / DocsError / FilesError / SecretsError:
- QueueError gains an explicit Forbidden variant (previously authz
denial was squashed into Rejected("forbidden") in queue_service.rs:68,
losing the structured variant a 403-translation layer would need).
- QueueError::Unavailable renamed → Backend.
- PubsubError::Unavailable renamed → Backend.
- InvokeError::Unavailable renamed → Backend.
- Call sites updated (queue_service, pubsub_service, invoke_service,
Noop* stubs, From<PubsubRepoError> impl, one test assertion).
- New unit test verifying authed-denied → QueueError::Forbidden.
AUDIT.md anchor: F-Q-004.

shared/invoke.rs introduces the InvokeService trait + InvokeTarget enum:
- InvokeTarget::Path(String) — resolves via the route trie
- InvokeTarget::Name(String) — (cx.app_id, name) -> script_id via get_by_name
- InvokeTarget::Id(ScriptId) — direct lookup
InvokeService::resolve enforces same-app at the service layer
(InvokeError::CrossApp). InvokeService::enqueue_async writes a v1.1.9
OutboxSourceKind::Invoke row for fire-and-forget composition.
Errors: NotFound, CrossApp, DepthExceeded(u32), Forbidden, Rejected,
Unavailable. NoopInvokeService surfaces all calls as Unavailable for
harnesses that don't wire the service.
ScriptRepository gains get_by_name(app_id, name) backed by the existing
(app_id, name) uniqueness constraint. Postgres impl + in-memory mock +
the picloud crate's PostgresScriptRepoHandle delegate added.
Services::new gains invoke: Arc<dyn InvokeService> positionally after
queue. with_noop_services wires NoopInvokeService. 12 test sites
threaded through. picloud/lib.rs binds NoopInvokeService at this commit
boundary — the real InvokeResolver lands in commit 8.
Deviation from plan (flagged for HANDBACK §7): the plan called for
moving ExecutorClient + ScriptIdentity from orchestrator-core to shared
so the invoke bridge could call a re-entrant variant. Re-evaluated:
the bridge lives in executor-core which can hold Arc<Engine> directly,
making the trait move unnecessary. Engine::execute is sync, returns
ExecResponse, and shares the engine instance + per-call SdkCallCx
exactly as required. AST cache reuse across invokes is a v1.2 optimization
(invokes recompile each call — ms-scale cost, acceptable).
