Linear: SB-2012

What I did

Remove the leftover Svelte docs source-decorator deprecation for parameters.component. Since Storybook 7 that path only warned; wrapper stories already generate source from context.component (the meta component). Document the removal in MIGRATION.md.

Out of scope (owned by Svelte Docgen / Agent-ready Svelte): legacyTemplate and other Svelte CSF legacy removals.

Checklist for Contributors

Testing

The changes in this PR are covered in the following automated tests:

• stories
• unit tests
• integration tests
• end-to-end tests

generateSvelteSource coverage in sourceDecorator.test.ts is unchanged. The removed branch was a console deprecation only and had no dedicated assertion.

Manual testing

Caution

This section is mandatory for all contributions. If you believe no manual test is necessary, please state so explicitly. Thanks!

1. Inspect the diff for code/renderers/svelte/src/docs/sourceDecorator.ts. Confirm the deprecate(...) call and parameters.component check are gone, and that @wrapper stories still assign component = ctxComponent.
2. Run git grep -n "parameters.component is deprecated" -- code. Expect no matches.
3. Optionally open a Svelte sandbox Docs page for a story that uses a @wrapper render component and a meta component. Confirm the Code panel still shows the meta component, not the wrapper.
