Pull Request Overview

This PR enhances the minifier's ability to fold object spread operations by expanding the detection of expressions that can be safely removed from spread operations. The change consolidates the logic for determining when spread elements should be folded and extends support to include evaluated expressions that resolve to non-string values.

• Refactored spread element folding logic into a reusable helper function
• Extended folding support to expressions that evaluate to non-string values without side effects
• Added test coverage for logical NOT operations (!0 and !1)
