Preserve inline CSF3 story parameters in full-source preset

[Copilot]

babel-preset-storybook-full-source treated CSF3 stories with inline parameters as missing parameters, then appended Story.parameters = {} before assigning fullSource. This dropped existing Storybook metadata such as docs.description.story.

• Parameter detection

  • Detects inline parameters on CSF3 object story exports.
  • Handles TS-wrapped story initializers such as as and satisfies.

• Regression coverage

  • Adds a typed CSF3 fixture matching the reported Meta / StoryObj pattern.
  • Updates existing CSF3 fixture expectations so inline parameters are preserved.

export const Default: Story = {
  render: () => <div>Example</div>,
  parameters: {
    docs: { description: { story: 'Description' } },
  },
};

// generated augmentation now preserves Default.parameters
Default.parameters.fullSource = '...';

• Fixes bug: babel-preset-storybook-full-source overwrites inline CSF3 story parameters #36660

lets also add a test for StoryFn with parameters if we don't have such yet:

type Story = StoryFn<typeof meta>;

export const Default: Story = () => <div>Example</div>;

Default.parameters = {
  docs: { story: {  docs: { description: { story: 'Description' } } }
}

Addressed in 4af77918: updated the Beachball comment wording and added StoryFn parameters regression coverage. Focused validation passed for test, format, type-check, lint, and secret scanning.
