v0.0.58

A working copy now refuses duplicate and cardinality-breaking edges before it queues them, and can check an edge move in advance.

Core

• Added: A working copy refuses an edge write that the server would refuse as a duplicate or because an end already holds its one edge, so you learn of it at once instead of when the write is sent. Docs
• Added: You can check whether moving an edge's end would be refused, without queuing anything, to disable a drop target before the person tries it. The Swift and Node bindings gain checkEdgeMove.
• Changed: An edge refusal from a working copy now carries the same details the server gives for the same write, so an app can tell a duplicate (details.constraint is duplicate) from a full end (cardinality). The Swift MarfaError.validation case gains a details value, and the thrown Node error gains a details property. Docs

CLI

• Added: marfa device edges check-move <ID> (--source <ID> | --target <ID>) answers what the matching edge move would, and queues nothing.
• Changed: The error output carries the refusal's details in error.server.details.
