Edit Blueprint Switch Cases

Recommended sequence:

1. blueprint.graph.inspect with view: "overview" to find the switch node.
2. If the node has hasNodeEditCapabilities: true, call blueprint.node.inspect.
3. Read editCapabilities and current case pins.
4. schema.inspect for the needed blueprint.node.edit operation.
5. blueprint.node.edit to add, remove, or rename the case.
6. blueprint.compile.

Use blueprint.node.edit for cases. Use blueprint.graph.edit for links and pin defaults around the node.
