Function getMalAccessToken

getMalAccessToken(
request: MalAuthorizationCodeRequest,
): Promise<MalTokenResponse>
getMalAccessToken exchanges a MAL authorization code for an access token through PKCE.

It completes the flow started by buildMalAuthorizationUrl using the MalAuthorizationCodeRequest fields and returns a MalTokenResponse consumed by MalCredentials and buildMyAnimeListApi. Transport is shared with RequestOptions.
Parameters
- request: MalAuthorizationCodeRequest
  The authorization-code fields and optional transport settings; a MalAuthorizationCodeRequest.
Returns Promise<MalTokenResponse>
The MalTokenResponse for the authenticated session.
Throws
TypeError when codeVerifier is not a valid MAL PKCE verifier.

Throws
AniLinkApiError when MAL rejects the grant, or AniLinkNetworkError on timeout, cancellation, or network failure; both carry sanitized token-request details.
Example
```
const token = await getMalAccessToken({ clientId, code, codeVerifier });
// token.access_token -> pass as MalCredentials.accessToken to buildMyAnimeListApi
```
