Pull Request Overview

This PR fixes the wrapping behavior in noWrapBeforeImport mode so that the first import is correctly processed when there is no code before it.

• Adjusts the conditional logic in visitor.js to handle the first import and its preceding node more explicitly.
• Adds a check in wrapper.js to set the reachedFirstImport flag when no node is marked with lastBeforeWrapping.
• Updates tests and snapshots to validate the updated wrapping behavior.

• Ensure that the variable 'reachedFirstImport' is declared in the appropriate scope before being assigned; currently, the diff does not show its declaration, which could lead to a runtime ReferenceError.

[nitpick] Consider clarifying in the comment that when path.key equals 0 no marking takes place because there is no valid previous node, to improve maintainability and ease of understanding of this special case.

Suggested change

	// for the first element there is a special case as we can't mark the previous one
	// therefore we do not mark anything to make clear that there's nothing to exclude
	// For the first element, there is a special case: when path.key === 0, we can't mark the previous node
