What matters most in this codebasee.g. Correctness first; we avoid new dependencies for small utils

Example input

task: Add a slugify(title) util for blog post URLs: lowercase, ASCII only, words joined by hyphens, max 60 characters, no leading or trailing hyphen.
priorities: Correctness first. We avoid new dependencies for small utilities unless there's a clear reason.
attempt_a:
```ts
export function slugify(title: string): string {
  return title
    .toLowerCase()
    .normalize("NFKD")
    .replace(/[̀-ͯ]/g, "")
    .replace(/[^a-z0-9]+/g, "-")
    .replace(/^-+|-+$/g, "")
    .slice(0, 60)
}
// tests: "Hello World" -> "hello-world"; "Café crème" -> "cafe-creme"
```
attempt_b:
```ts
import slugifyLib from "slugify" // new dependency added to package.json
export function slugify(title: string): string {
  const s = slugifyLib(title, { lower: true, strict: true })
  return s.length > 60 ? s.slice(0, 60).replace(/-+$/, "") : s
}
// tests: basic words; accents; punctuation stripped; exactly 60 chars; 61 chars cut at a hyphen with no trailing hyphen
```
