The interval split mode looped for (i = 0; i < totalPages; i += interval),
which spins forever when interval <= 0. Both the single-file dialog and the
batch dialog can reach it (the batch dialog's validateOperationData only
checks truthiness, so -1 passes). Guard at the source in the main process:
reject non-positive or non-integer intervals before the loop, protecting
both paths and any future caller.

Adds pdfGetFormFields (lists AcroForm fields with name/type/value) and
pdfFillForm (fills text fields by name, optionally flattens) to
PDFOperations.js, dispatched via 'formFields'/'fillForm' in
executeOperation. pdfFillForm skips unknown/non-text fields per-field
(logs + continues) rather than failing the whole batch, matching the
partial-success precedent set by pdfExtractImages.
Wires a "Fill Form" entry into the PDF editor dialog: selecting a PDF
fetches its fields via a new get-pdf-form-fields/pdf-form-fields IPC
round trip and renders one text input per field, plus a flatten
checkbox, following the same structure as the crop/pageNumbers dialogs.

Adds four new PDFOperations: pdfExtractText (pdfjs-dist getTextContent),
pdfAddPageNumbers (reuses pdfWatermark's position-mapping logic, extracted
into a shared resolvePosition helper), pdfCrop (page.setCropBox against the
existing MediaBox), and pdfExtractImages (pdfjs-dist operator list +
paintImageXObject + sharp). Wired into executeOperation's switch and the PDF
editor dialog UI (4 new sections/toolbar buttons/menu items) with no new IPC
channel needed.
pdfjs-dist v5 is ESM-only, so it's loaded via dynamic import() of its
Node-friendly legacy build; Jest needs --experimental-vm-modules to support
that, so the test scripts now set NODE_OPTIONS accordingly via cross-env.
