feat(export): allow setting paper size in pdf export

[Galaxy102]

Hello,

for non-US fellas using Letter as paper format is pretty uncommon. Thus I thought it would be great if you could pass the PDF paper size as an option.

Please let me know about anything improvable, Javascript is not my main programming language.

Cheers!

@Galaxy102 thank you for this — a --papersize flag for PDF export is a clean, well-scoped feature (the hardcoded Letter default has annoyed A4 users for years), and your implementation threading it through to page.pdf() is exactly right. This is one of the PRs from this repo most worth porting forward.

Here's the context: JSON Resume is under active maintenance again (2026), and resume-cli has been revived — but the codebase moved into the jsonresume.org monorepo at packages/cli (merged in jsonresume/jsonresume.org#278). This standalone repo is being archived with a redirect, so PRs against it can no longer land — which is why I'm closing this rather than merging it.

If the change still matters to you, we'd genuinely welcome a re-submission against packages/cli in the monorepo — the maintainers are active there and PRs get reviewed. Announcement: #786 · Consolidation: jsonresume/jsonresume.org#275. Thanks again for contributing during the years when this repo was quiet — it didn't go unnoticed.
