OutboundService.send is now opt-in idempotent: an explicit idempotencyKey routes
the send through IdempotencyService.run (Slice 6), so reusing a key with a
different target/payload returns a 409 conflict and a same-key/same-request retry
replays the cached command. The inner findUnique early-return stays as a backstop
so a FAILED-then-retried send never collides on the command's unique key. Keyless
sends keep the old behavior (no ledger row).

Task 9.3: OutboundService now delegates the execute step to CapabilityBroker
(policy-gated + obligation-enforced) instead of calling a provider directly, while
keeping idempotency + rate-limit + the command/attempt ledger. BLOCKED obligations
→ command BLOCKED; a fail-closed throw marks the command FAILED then propagates.
AdaptersModule imports CapabilityModule; P4/P6/P8 egress now flows through the
broker unchanged. Updated 6 spec constructions; added a DENY_OUTBOUND test.
