Fix CI and prep 2.1.3 for AppState 3.0

macOS and DocC were failing because runners no longer ship Xcode 16.
Switch those workflows to macos-15 + latest-stable (same as AppState).

Also polish the #30 fixes for release: unwrap before collection casts
on Linux/WASI, import Combine when available, and document 2.1.3 so
AppState can drop its Cache revision pin.

+## [Unreleased]
+
+## [2.1.3] - 2026-07-17
+
+Release intended for consumers such as **AppState 3.0**, which can replace a revision pin of Cache#30 with `from: "2.1.3"`.
+
+### Fixed
+
+- **WebAssembly / WASI builds** — Guard `@Published` / `ObservableObject` with `#if canImport(Combine)` instead of `#if !os(Linux) && !os(Windows)`, so wasm no longer takes the Combine path ([#30](https://github.com/0xLeif/Cache/pull/30), AppState#149).
+- **Linux / WASI collection cast crash** — `Dictionary.get(_:as:)` unwraps the optional value before casting, avoiding `swift_dynamicCastFailure` / `_arrayForceCast` aborts when reading collection-typed values from an `Any` cache ([#30](https://github.com/0xLeif/Cache/pull/30), AppState#151).
+- **CI** — macOS and DocC workflows no longer pin Xcode 16 (unavailable on current `macos-latest` images). Use `macos-15` with `latest-stable` Xcode, matching AppState.
+
+### Changed
+
+- Explicitly import Combine when available so `@Published` / `ObservableObject` compile reliably across build configurations.
+
+## [2.1.2] - 2025-09-20
+
+### Added
+
+- DocC plugin dependency and GitHub Pages documentation workflow updates.
