**Update `AvatarGenerationResult` to include required generator contract fields.** The response structure at lines 120-139 (and across all models) is missing the required fields per coding guidelines. `AvatarGenerationResult` must include `content` (with url, file_name, file_size), `generation_time`, `parameters`, and `local_path` keys. Currently it only has `video_url`, `processing_time`, and other fields that don't match the contract. This affects the entire generator module and all model implementations that return this result type.

```
In `@packages/providers/fal/avatar-generation/fal_avatar/models/grok.py` around
lines 120 - 139, The AvatarGenerationResult returned in the grok model must be
updated to include the generator contract fields: replace/augment the current
return in the method that constructs AvatarGenerationResult (look for
AvatarGenerationResult(...) in grok.py using self.model_name and
self.estimate_cost) so it includes a top-level content dict with keys url,
file_name and file_size (populate from
video_info.get("url"/"file_name"/"file_size")), a generation_time field (use
response.get("processing_time") or compute appropriately), a parameters field
(include the input arguments/parameters used, e.g., arguments or relevant
request params), and a local_path field (path to downloaded file or None); keep
existing fields like cost, model_used, metadata, success but ensure the new keys
match the required contract across all generator implementations.
