refactor(value): align native type checks with quickjs-ng

[buke]

• switch promise, typed array, and array buffer detection to native quickjs-ng APIs
• add native collection, proxy, and immutable ArrayBuffer helpers with regression tests
• cover value.go changes with focused tests and coverage validation

Code Review

This pull request introduces support for Proxy objects, adds immutability controls for ArrayBuffers, and implements several new type predicates such as IsRegExp, IsMap, and IsProxy. It also refactors existing type checks and the ToUint8Array method to use native QuickJS functions for better efficiency. A critical bug was identified in the NewProxy implementation where target and handler references are consumed by the underlying C function without being incremented, which would lead to double-free errors during garbage collection.

Code Review

This pull request introduces several new methods and predicates to the Context and Value types, including support for Proxies (NewProxy, ProxyTarget, ProxyHandler), immutable ArrayBuffers, and various JavaScript built-in types like Map, Set, and RegExp. It also refactors TypedArray detection and ToUint8Array to use native QuickJS functions. Feedback was provided to ensure ToUint8Array checks for a valid context to prevent panics, to correct the logic in typedArrayType regarding JS_TYPED_ARRAY_NONE, and to maintain consistency in boolean conversions.
