Pull request overview

This PR fixes the auto-fixer for the no-single-promise-in-promise-methods linter rule to correctly preserve array structure when fixing Promise.all calls with single-element arrays.

Key Changes:

• Modified the fixer to replace await Promise.all([x]) with [await x] instead of await x, preserving the array return type
• Changed from tracking a boolean flag to capturing the await expression's span for more precise code replacement
• Added differentiated handling: Promise.all preserves array structure while Promise.any and Promise.race maintain single-value semantics
