Unit tests for slugify #95

What

slugify in lib/projects.ts makes URL slugs for projects.

There are no tests for it yet.

Cover at least

• lowercases and hyphenates: "My Cool App" → my-cool-app
• accents are stripped: "Café Résumé" → cafe-resume
• leading, trailing and repeated separators are collapsed
• the result is capped at 60 characters
• an all-symbol or empty title → "project"

How

• Create lib/projects.test.ts next to the code. Follow the style of lib/github-auth.test.ts.
• Run npm test. Then break the code on purpose (flip a condition) and watch at least one of your tests fail. Paste that failure output in the PR description, then undo the break.
• Test behaviour through the exported function only. Don't change the source file unless you find a bug, and if you do, stop and comment on this issue first.

Size: ~30–60 lines of tests, 0 lines of source.
