PdfCompressionTask class abstract
A single optimisation job. The source bytes remain owned by the caller.
Web jobs use a dedicated instance of the configured PDF render-worker
script, so cancelling a job never interrupts the viewer's workers. Hosts
must bundle the current worker and configure pdfRenderWorkerScriptUrl
(normally through registerBundledEditorAssets). Worker failures are
reported through result; optimisation never falls back to the UI thread.
