0.9.3

Changed

• Added true browser batch execution for JavaScript, TypeScript, Python, C#, and C++ so multi-case runs prepare or compile once and execute the full input batch in one worker call.
• Kept JavaScript, TypeScript, and Python batch cases isolated with fresh globals and freshly materialized mutable inputs, including linked-list/object inputs that user code can mutate.
• Added compile-once browser batch drivers for C# and C++ named-function, solution-method, and ops-class execution paths.

Fixed

• Fixed Python browser batch handling for default imports, script-mode inputs, and custom class materialization.
• Added regression coverage for batch global isolation, mutable input isolation, C# browser batch execution, and C++ compile-once batch behavior.
