The typo is visible in the rendered project card copy on the homepage.

Validation pass for this branch:

• Confirmed the only source change is src/data/projects.js.
• Imported projectList in Node and confirmed Litefy now contains lightweight and no longer contains lighweight.
• Ran GITHUB_TOKEN=... pnpm build; Astro built both routes successfully.
• Checked generated dist/index.html: corrected Litefy copy present, old typo absent.
