@kbn/workflows-yaml

Shared utilities for parsing, validating, and serializing Kibana workflow definitions written in YAML.

The package provides:

• YAML parsing — convert workflow YAML to JSON (with or without schema validation), extract document errors, and stringify definitions back to YAML with a stable key order.
• Liquid templating — a cached Liquid engine plus helpers to validate templates and pinpoint error positions inside expressions.
• Regex helpers — shared patterns and predicates for variables, property paths, and Liquid blocks/tags used by the editor and runtime.
• Zod helpers — type inference, human-readable type descriptions, and error formatting/enrichment for connector and workflow schemas.
• Typed errors — InvalidYamlSchemaError, InvalidYamlSyntaxError, WorkflowValidationError, and WorkflowConflictError with type guards.
