eb79ef0: Flow steps can reference channels (channel: { id, version }), drawn as channel nodes with a link to their docs. A step's title is now optional and defaults to the name of what it references (or the actor, external system or custom node's name, or the step's id); a custom node's title defaults to the step's title. Mistakes in flows no longer fail silently: unknown step properties fail the build (custom ones must start with x-), steps that use two node types or both next_step and next_steps fail with a message naming the step and what to change, and a next_step to a step that doesn't exist, or a reference to a resource that isn't in the catalog, logs a warning naming the flow and step. The step type field is still accepted but ignored. The linter checks the same rules, adds refs/flow-step-exists for next steps that aren't in the flow, and checks channel references in flow steps. The SDK adds FlowBuilder.addChannelStep, channel on FlowStep, an optional title, and accepts system and channel references when parsing an index.
