isolated(any) and #isolation: Letting Swift Closures Automatically Inherit Isolation

Swift 6 introduced many new features and keywords for concurrency. While many of these might be rarely used in daily development, encountering specific scenarios without understanding these new concepts can lead to hitting a wall, even with AI assistance.

These tools enable function isolation inheritance, allowing the compiler to automatically infer the execution context of closures.
