Make AnyType Sendable

[KVSRoyal]

Note

Contribution originally by @JJ-Intuit
This is a clone of #782 that is a direct branch of player, rather than a fork. Forks don't run on CI/CD properly.

What

This PR makes the AnyType enum conform to the Sendable protocol by removing all Any-based APIs and using only recursive AnyType values. This enables safe usage across Swift concurrency boundaries but introduces breaking changes for code that relied on Any interoperability.

See "Release Notes" for full description. (Moved there to avoid redundancy.)

Why

With Swift 6's strict concurrency checking, AnyType needed to be Sendable to be used safely in concurrent contexts.

Release Notes

Breaking Change: .anyArray and .anyDictionary use AnyType

The AnyType enum now conforms to Sendable protocol and is concurrency-safe. This required removing all APIs that depended on the Any type:

// Before
case anyDictionary(data: [String: Any])
case anyArray(data: [Any])

// After  
case anyDictionary(data: [String: AnyType])
case anyArray(data: [AnyType])

Migration

Use AnyType cases directly instead of converting from/to Any:

// Old (removed)
let anyType = AnyType.anyDictionary(data: ["key": "value"])
let anyArray = AnyType.anyArray(data: ["key", 2])

// New (Sendable-safe)  
let anyType = AnyType.anyDictionary(data: ["key": .string(data: "value")])
let anyArray = AnyType.anyArray(data: [.string(data: "key"), .number(data: 2)])

Breaking Change: AnyType will only decode .unknownData with AnyTypeDecodingContext

Users are required to provide AnyTypeDecodingContext when attempting to decode anyArray or anyDictionary. The decoder will throw if we need the context but one is not provided. As a side effect of this, .unknownData will only be returned when a context is provided. For example:

// Before, decoding data = "null"
let anyType = try? JSONDecoder() // no context
    .decode(AnyType.self, from: data) // This will return .unknownData

// After, decoding data = "null"
let anyType = try? JSONDecoder() // no context
    .decode(AnyType.self, from: data) // This will throw an error

let anyType = try? AnyTypeDecodingContext(rawData: data) // with context
            .inject(to: JSONDecoder())
            .decode(AnyType.self, from: data) // This will return .unknownData

Breaking Change: AnyTypeDecodingContext.objectFor is no longer public.

All decoding of AnyType is now handled internally. So AnyTypeDecodingContext.objectFor(path: [CodingKey]) throws -> Any is no longer exposed to users.

New Features

Added as<T>(_:) convenience method and AnyType (anyDictionary) subscripting for type-safe value extraction:

// Before
if case let .anyDictionary(myDict) = anyType,
    let title = myDict["title"] as? String {
    // Do a thing
}

// After
let title: String? = anyType["title"]?.as(String.self)
