Pull request overview

This PR refactors the validation of specifiers and rewrites the rewrite policy logic to make --validate-specifiers policy-derived by default, removing explicit boolean defaults and inferring the setting from --rewrite-policy (enabled for safe and warn, disabled for skip). The changes also add validation to prevent disabling --validate-specifiers when --rewrite-policy is set to safe.

Key changes:

• Removed explicit validateSpecifiers: true defaults and made it policy-derived (on for safe|warn, off for skip)
• Added validation to prevent --no-validate-specifiers when --rewrite-policy is safe
• Added comprehensive unit tests for new validation behaviors
