Walkthrough

This pull request introduces a new public validation API function isValidScriptlet for validating scriptlet code. The implementation adds isValidScriptlet(code: string) in src/util/validators.ts alongside an internal helper prepareScriptlet that configures expression handling. The function is exported from src/index.ts and includes a corresponding test suite covering single-line expressions, continuation lines, ternary operations, and group termination scenarios. A changeset entry documents the minor version bump.
