fix(plugin-seo): type Meta.image and extract shared MetaImageValue

[Notorious-Ali]

What?

Replaces the untyped image?: any on the plugin's Meta type with a precise type, and extracts a shared MetaImageValue type so that Meta.image and GenerateImage 's return value can no longer drift apart.

Why?

Meta.image was typed any

How?

In packages/plugin-seo/src/types.ts:

• Added a new exported type:

  export type MetaImageValue = { id: number | string } | number | string

• Meta.image is now image?: MetaImageValue instead of any.
• GenerateImage's return type now reuses MetaImageValue | Promise<MetaImageValue> — structurally identical to the previous inline union, so there is no runtime/behavior change.

In packages/plugin-seo/src/exports/types.ts:

• Re-exported MetaImageValue from the public types barrel so consumers can type image values consistently.

Before:

export type Meta = {
  description?: string
  image?: any // TODO: type this
  keywords?: string
  title?: string
}

After:

export type MetaImageValue = { id: number | string } | number | string

export type Meta = {
  description?: string
  image?: MetaImageValue
  keywords?: string
  title?: string
}
