…nd JIT edge cases Add tests covering previously uncovered paths in src/vm/mod.rs and src/vm/jit_cranelift.rs: - Arena-full fallback: OP_RECNEW and OP_RECWITH heap fallback when 64KB bump arena is exhausted (7 tests creating 3000+ records in loops) - Arena record to Value conversion and to_value_with_registry paths - Multi-frame OP_RET: 3-4 level deep call chains returning through multiple stack frames, including record returns across frames - JIT: OP_ROU (round builtin), zero-arg OP_CALL via bytecode injection, record return arena promotion, OP_RECWITH, and foreach/OP_LISTGET
