v0.9.0

What's New

AnyDataMarshaler — render arbitrary data, not just TableData

New RenderAnyData() dispatch for rendering any Go value. JSON, YAML, and TOML register handlers automatically.

output.RenderAnyData(myStruct, output.FormatJSON, output.RenderOptions{})

All 16 formats now dispatch via RenderTableData()

D2, DOT, Mermaid, and PlantUML now register TableDataMarshaler via init(). Previously only 10 formats were registered.

Generic formatRegistry[T]

Thread-safe generic registry replaces 3 separate mutex+map patterns. Same formatRegistry[T] backs shape capabilities, table-data marshalers, and any-data marshalers.

AddRowChecked

err := data.AddRowChecked(row) // returns ErrColumnMismatch if column count differs from headers

NOM event constants

nom.EventWorkflowStarted  // instead of "workflow.started"
nom.EventActivityCompleted // instead of "activity.completed"
