feat(files): add Markdown PDF export

[BillLeoutsakosvl346]

Summary

Adds a browser-native Save as PDF… action for open Markdown files.

• Keeps the existing Download action unchanged and places the Markdown-only PDF action directly after it
• Reuses the rendered rich Markdown editor and window.print() with the file name as the temporary document title
• Applies scoped print styling for a light, paginated document while hiding application and collaboration chrome
• Adds no dependencies, API routes, server-side generation, or shared component changes

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation
• Other

Testing

Automated checks:

• bunx biome check --no-errors-on-unmatched --files-ignore-unknown=true on the three changed files
• cd apps/sim && bun run type-check
• git diff --check

Local smoke checks:

• Confirmed the localhost app responds successfully on port 3000
• Self-reviewed Markdown-only gating, action ordering, title restoration, and isolation of the existing Download, Share, and Delete handlers

A dedicated button-level test was intentionally not added because equivalent Files header actions do not have button-level tests. Browser print-preview testing and screenshots were not available from this session because no controllable browser was attached. Reviewers should manually verify dialog cancellation, suggested filename, both app themes, non-Markdown gating, and a multi-page document with headings, lists, code, tables, links, and images.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (not added; rationale above)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

Screenshots/Videos

Not available from this session; browser automation reported no attached browser.

PR Summary

Low Risk
Client-only print/export with DOM cleanup; no auth, persistence, or API changes. Residual risk is print-preview quirks across browsers and themes, not data or security.

Overview
Adds a Save as PDF… action for open Markdown files in the Files header (right after Download), using the browser print dialog with no new server or dependencies.

The rich Markdown editor reports when its content is loaded and safe to print; the action stays disabled until the current file is ready. Export marks the editor root with print attributes, temporarily sets document.title from the file name (extension stripped), calls window.print(), and restores title and DOM flags on afterprint or error.

Scoped @media print rules hide app and collaboration UI and style the active markdown surface as a light, paginated document (typography, code blocks, tables, images).

Closing as superseded. The replacement will implement direct Markdown-to-PDF generation and download instead of browser print preview.
