PdfDocumentActionSink class abstract

The write half of the Document-AI seam: the editing actions an agent can drive, decoupled from any particular model or transport.

This is an interface stub, host-provided. dart-pdf does not ship an agent. A host implements this over the existing editing surface (a PdfEditor, or the editing controller in dart_pdf_editor) and wires it to whatever model loop it runs — the model proposes actions against a PdfDocumentContext, the host validates them and calls these methods.

Implementations decide their own persistence (incremental save, undo stack) and may reject or clamp out-of-range requests.
