Angular store signals previously lagged behind writes, and the advertised framework ranges accepted untested future majors. This adds synchronous Angular signal updates with lifecycle-safe cleanup, preserves Angular's native zoneless rendering schedule and ordinary core subscription batching, and validates the supported version floors against packed consumers.

• Support stable Angular 22 (^22.0.0), with the example and development toolchain pinned to 22.2.3. Cover inputs/caret, computed values, keyed lists, zoneless updates, independent consumers, and teardown.
• Bound React to 18/19, Vue to 3.2–3.x, and Svelte to 4/5. Fix Vue 3.2.0 declaration compatibility by exposing Ref<Snapshot<T>> while retaining a shallow ref at runtime.
• Add focused packed-consumer CI for Angular 22.0.0/22.2.3, Vue 3.2.0, and Svelte 4.0.0/5.0.0; include React 19.0.0 in the existing compatibility and Compiler matrices. Update examples, README/public docs, and minor changesets for 0.10.0.

Migration: Angular 21 and earlier are no longer supported; keep Angular runtime/compiler packages aligned on a stable Angular 22 release. Future unsupported framework majors are excluded. Existing adapter import paths and call signatures remain unchanged.

Validation: 564 unit tests passed; 154 browser tests passed with 8 existing clipboard skips. Packed Angular consumers passed 36 browser checks total; Vue/Svelte minimum consumers passed 36. React packed compatibility passed on 18.0.0, 18.3.1, 19.0.0, and 19.3.1, including the existing Compiler matrix. TypeScript, lint, library and Angular/Vue/Svelte example builds, docs build, and frozen Bun install passed. GitHub CI will verify the complete release candidate before merging.
