v0.66.13

Guarded acceptance for collaborative agents

The package now includes a copyable acceptance module that prepares immutable proposals, reconciles durable Git receipts, and lists pending work for recovery. The accompanying guide explains client-bound read evidence, ownership changes, and the boundary between Ablo acknowledgement and external application.

Applications supply their own trusted verification and protected Git broker. This release adds example source and documentation; it requires no Ablo server deployment and introduces no breaking SDK changes. See the integration example and acceptance guide.
