Note

Medium Risk
Releases bundled storage and API surface changes; walletkit-db drops/rehomes former SQLite public types (Connection, cipher, etc.) to walletkit-sqlite, which breaks semver for direct walletkit-db consumers.

Overview
Release v0.22.0 — bumps the workspace and all published crates (walletkit, walletkit-core, walletkit-db, walletkit-sqlite, CLI, bindgen, xtask) from 0.21.4 to 0.22.0 in Cargo.toml, Cargo.lock, and internal path dependency versions.

Adds a 0.22.0 changelog entry documenting what ships in this release: credential activity history improvements, encrypted WASM SQLite persistence in OPFS, the walletkit-sqlite split from walletkit-db, credential activity history store, and updated Worldchain URLs. This PR does not change application logic—only version metadata and release notes.
