feat: Extract multiple example code blocks

[Mrtenz]

This updates the RPC extraction script to support multiple code blocks in a single @example tag. This can be used to, for example, have a manifest and usage within the same example:

/**
 * @example Title
 * ```json name="Manifest"
 * {
 *   "initialPermissions": { ... }
 * }
 * ```
 * ```ts name="Code"
 * // Usage of the permission etc.
 * ```
 */

Which will now be extracted as:

{
  "examples": [
    {
      "title": "Title",
      "examples": [
        {
          "name": "Manifest",
          "language": "json",
          "content": "..."
        },
        {
          "name": "Code",
          "language": "ts",
          "content": "..."
        }
      ]
    }
  ]
}

Note

Medium Risk
Changes the generated schema shape for method examples and the JSDoc parsing regex, which may break downstream consumers or fail on previously tolerated formatting edge cases.

Overview
Enhances the generate-schema.mts extraction logic so a single JSDoc @example tag can contain multiple fenced code blocks, each optionally labeled via name="...".

This changes the emitted method example shape from a single {language, content} to { title, examples: [...] }, formats each block via Prettier using its declared language, and extracts the optional example title separately from the code blocks.
