Recognizes Vec3-shaped object schemas ({x, y, z} number properties)
structurally in RimWorkflowDescribeTools and dispatches them to a new
RimWorkflowVec3Binding in RimWorkflowTaskInput::createBinding(). Stores
the value as a cvf::Vec3d field, parses JSON object defaults, and emits
a YAML flow-mapping ({x: .., y: .., z: ..}) matching the taskmaestro
Vec3 pydantic model shape.
Replace the rips.taskmaestro_helper introspect subcommand with
`python -m taskmaestro workflow describe --json`. RimWorkflowDescribeTools
converts the describe output (JSON schemas, depends_on, config_values)
into the workflow graph used by the Workflow UI. This also adds support
for collect dependencies and maps rips.Reservoir to EclipseCase pickers.
