Pdf support, fix model selector

[tanevanwifferen]

add pdf support for anthropic (pdfSupport is a property on IChatModel, can be implemented for other models too)
fix bug where the default model was always returned, so it could never be overwritten

Bug in pdf support is that the PDF doesn't show up in electron. A base64 string can't be larger than 2mb? or it won't show up in the electron renderer. Not sure how to fix that for now. Maybe render an image of the first page, or show an icon. For now it shows an empty iframe

Key changes include updating markdown handling to allow iframes for PDF display, modifying service logic to process documents (PDFs) via base64 or URL, and extending model/provider configurations to support PDF.

• Consider adding a check to verify that splitting the base64 string using a comma always yields a valid value. This could prevent potential issues if the input format unexpectedly changes or does not contain a comma.

data = item.data.split(',')[1]; // remove data:application/pdf;base64,

• Review whether the commented-out ingest call is intentional. If it's a temporary debugging change, consider adding a comment explaining its purpose or removing it before production.

Hey, bro, it's really appreciate your work. Currently, I'm about to merge a major dev branch (feat/folder) into main that contains significant changes(including the bug fix you mentioned here, also updated the model definition in the Provider configuration. The model's display now uses the label, while the value is based on the key of each mode).

I plan to release a new version this week, now merging the PR would introduce some conflicts, given that PDF support still has some issues, could we submit the PR to the feat/claude-pdf-support branch? We can release it after further improvements.

[tanevanwifferen]

that's an option. otherwise I can also merge main once you're done, fix the conflicts myself. Whatever you want

[nanbingxyz]

The latest code has been merged into the main branch. Could you please resolve any merge conflicts and resubmit? Let me know if you need assistance.

@nanbingxyz I'm trying to merge, but there's a bunch of husky errors? Can I skip it in some way?

We use Husky to keep improving our code quality, though you can skip it if your code is well-tested.
