Implement eval() as a sentinel-intercepted builtin that parses and executes code strings at runtime with proper scope and strict mode handling. Direct eval inherits caller scope (vars leak in non-strict), while indirect and strict eval contain declarations via function scope. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
