**Update default output directory from `"output"` to `"result_folder"`** across the fal image-to-video package to align with repository guidelines.

The CLI default at line 39 and related defaults in `generator.py` (line 69), `file_utils.py` (line 28), and test files all use `"output"`, conflicting with the repository guideline: "Store generated video outputs in result_folder/ directory". This is a systematic issue affecting multiple files in the package for consistency with the google/veo provider which already follows this pattern.

<details>
<summary>✏️ Changes needed</summary>

- `cli.py` line 39: `default="output"` → `default="result_folder"`
- `generator.py` line 69: `ensure_output_directory("output")` → `ensure_output_directory("result_folder")`
- `file_utils.py` line 30: `output_dir = "output"` → `output_dir = "result_folder"`
- Update any hardcoded `"output"` references in tests and legacy `fal_image_to_video_generator.py`

```
In `@packages/providers/fal/image-to-video/fal_image_to_video/cli.py` at line 39,
Change hardcoded default output directory values from "output" to
"result_folder": update the CLI option default in click.option (change
default="output" to default="result_folder"), modify the call to
ensure_output_directory("output") in generator.py to
ensure_output_directory("result_folder"), set output_dir = "result_folder" in
file_utils.py, and search for any other literal "output" usages (including tests
and fal_image_to_video_generator.py) and replace them with "result_folder" so
all functions and utilities (e.g., ensure_output_directory, output_dir, CLI
click.option) consistently use the new directory name.
```
