feat(autoskills): add SWR support

[pedrocastellanos]

What Changed

• Added SWR dependency detection so projects using SWR are recognized automatically.
• Mapped SWR to install the Vercel plugin skill for SWR from the vercel-labs/vercel-plugin repository.
• Added/updated automated tests for SWR detection.
• Updated docs and website content to include SWR in supported technologies, plus new icons.

Why This Change

• SWR is widely used in React/Next.js projects and was missing from automatic skill recommendations.
• This ensures users get the correct SWR skill without manual setup.
• It keeps CLI behavior, tests, and documentation aligned.
