Summary

#78 merged into chore/pdfjs-6.5.438, but #77 had already merged that branch into master. The commit therefore never reached master, and #76 is still open. This PR brings the same commit, b582384, to master unchanged. The full description and review are on #78.

Closes #76.

The commit fixes four tests that passed whether or not their feature worked:

• should render the PDF file now opens a PDF the repository tracks and waits until a page is drawn.
• should not render PDF with wrong url now waits for documenterror and fails if pages load instead.
• should open the external file with base64 source now opens { data } and checks for the document's own text.
• defaults to resources that ship next to the runtime files now checks that the response isn't the dev server's HTML page.

It also removes the missing PDF from 14 tests that don't need a document. It drops Uint8Array from PdfViewerApplicationOpenParameters, because PDF.js 6 rejects it at runtime.

Validation

• A manual CI run on this commit passed 40 of 40 tests: https://github.com/missing-elements/pdfjs-viewer/actions/runs/42381774805. master has the same tree as the commit's parent, so merging this PR produces exactly the tree that run tested.
• Make the tests check what they claim #78 lists the local checks. They include pnpm test -- --run, also run with public/ moved away. Each rewritten test was checked to fail with its feature broken. pnpm exec tsc --noEmit and pnpm build also passed.

Checklist

• The change is focused and includes tests for behavior changes.
• Relevant tests and the build pass locally.
• Public API, behavior, or user-guidance documentation is updated where needed. The type now matches the docs, which already use open({ data }).
• Accessibility impact has been considered, including keyboard navigation and focus visibility. There are no UI changes.
• This pull request does not disclose a security vulnerability.
