fix: class 方法/访问器/constructor/prototype 属性描述符（非枚举/只读），新增 DEFINE_PROP_ATTRS/DEFINE_ACCESSOR_ATTRS
...
- opcode.rs/inst.rs/contract.rs/vm.rs/vm_dispatch_ctrl.rs：新增两个带 attrs 扩展字的 define 指令
（attrs bit0=writable, bit1=enumerable, bit2=configurable，与 PropAttributes 一致）
- class/method.rs：方法与非计算访问器改按规范非枚举安装（DefineMethod 语义）
- class/prototype.rs：proto.constructor 非枚举；ctor.prototype 三标志全 false（MakeConstructor）
- 效果：language/statements/class 1782 pass/948 fail -> 1910 pass/716 fail（+128/-232）

fix: ArraySetLength 收缩遇不可配置元素静默失败、ToPrimitive 异常透传与既有属性描述符缺省回填
...
- arr.length 收缩时若 [newLen, oldLen) 内存在不可配置元素，整个收缩失败且不做任何修改（sloppy 赋值静默 no-op），不再抛错或截断
- length 赋值 ToPrimitive（valueOf/toString）抛错时按主 dispatch 约定直接返回，避免二次抛 RangeError 覆盖原异常（S15.4.5.1_A1.3_T2）
- Object.defineProperty/defineProperties/create 对已有属性省略描述符字段时保持现有属性值（无显式 meta 按 DEFAULT_DATA 回填），修复 toReversed/toSorted/toSpliced/with length-decreased-while-iterating

feat: BigInt.prototype[Symbol.toStringTag] = "BigInt"
...
Adds the well-known @@toStringTag data property (writable:false,
enumerable:false, configurable:true) so Object.prototype.toString and
property descriptors match the spec. Remaining built-ins/BigInt failure
(Symbol.toStringTag.js verifyProperty) is blocked on String(Symbol)
support in the Symbol track.

fix: BigInt SUB/MUL with 0n no longer raise Division by zero
...
binary_arith! applied an unconditional is_zero() guard, so x - 0n and
x * 0n (and wrapped-object variants) incorrectly threw RangeError.
Only DIV/MOD legitimately reject BigInt zero divisors; SUB/MUL must
compute normally. test262 language/expressions/subtraction:
29/6 -> 30/5 (bigint-arithmetic now passes).
