docs migration - Getting Started with the Static Linux SDK

Source: documentation/articles/static-linux-getting-started.md
Proposed disposition: Migrate
Proposed destination: platform-guides/Sources/PlatformGuides.docc/static-linux-getting-started.md
Reviewer: @swiftlang/platform-steering-group

Note: The proposal recommends reviewing any changes with previous authors Alastair Houghton and Melissa Herry, and considering whether to rename or split the article into smaller pieces.

Checklist

• Create a GitHub issue to track this migration
• Determine disposition (suggested: Migrate) and confirm destination
• Create the platform-guides package in this repository (see note above)
• Update .github/CODEOWNERS to add /platform-guides/* with the Platform Steering Group
• Reach out to original authors (Alastair Houghton, Melissa Herry) for review coordination
• Review source for accuracy against current Static Linux SDK release
• Evaluate whether to keep as a single article or split into focused sub-articles (e.g., installation, building, packaging)
• Translate Jekyll markdown to DocC markdown format
  • Remove YAML front matter
  • Convert any Jekyll callouts to DocC-style callouts
  • Verify SDK installation commands and URLs
  • Verify build and link invocation examples
  • Update any Swift version references
• Add article (or articles if split) to PlatformGuides.docc/Documentation.md under a "Linux" topic group
• Run swift package generate-documentation --analyze --warnings-as-errors in platform-guides/
• Preview locally with swift package --disable-sandbox preview-documentation in platform-guides/
• Submit PR to this repository for platform steering group review
• After merge and publication: add redirect_to: in the swift.org source file's front matter

Start with documentation/articles/static-linux-getting-started.md and compare it with the proposed platform-guides/Sources/PlatformGuides.docc/static-linux-getting-started.md destination. Review the package, CODEOWNERS, and Documentation.md checklist items, then run the two Swift documentation commands in platform-guides/. Done means the article is migrated and validated for DocC, with the required review and redirect work identified.
