Add generated labels to social link transforms

[essential-randomness]

Add a generated label field to @fujocoded/zod-transform-socials social link output. This can be used as a user-facing label for the link text, list item label, etc.

Why

Without a label field, custom platforms or duplicate accounts on a platform have no central place to be specified or overridden. Cases include: distinguishing a personal social account vs an art social account; or giving a name to a custom site.

Example

Input:

contacts:
  - https://github.com/FujoWebDev
  - url: https://www.fujocoded.com/
    label: Official Website
    icon: lucide:globe
  - url: https://store.fujocoded.com
    label: Merch Store
    icon: lucide:shopping-bag
  - https://fujoweb.dev

Output:

[
  { url: "https://github.com/FujoWebDev", platform: "github", username: "fujowebdev", icon: "simple-icons:github", label: "github" },
  { url: "https://www.fujocoded.com/", platform: "custom", username: null, icon: "lucide:globe", label: "Official Website" },
  { url: "https://store.fujocoded.com", platform: "custom", username: null, icon: "lucide:shopping-bag", label: “Merch Store" },
  { url: "https://fujoweb.dev", platform: "custom", username: null, icon: null, label: “fujoweb.dev" },
]

Todo

• Add optional label?: string to object social input.
• Add label: string to transformed social output.
• Generate labels with this precedence:
  • explicit input label
  • known platform name when platform !== "custom"
  • fallback from url, stripping leading www.
