2.2.0

✨ Added

• ClientSettings.fromEnv(key:) — build client settings directly from an environment variable holding a KurrentDB connection string (defaults to SWIFT_KURRENT_DB_URL).

🔧 Fixes

• getMetadata() — now returns nil (instead of throwing internalClientError) when the stream's $$<stream> metastream doesn't exist yet, matching the documented behavior.

📝 Docs

• Documented ClientSettings.fromEnv(key:) in the README and Getting Started guide.
