+sprout-proxy E2E test using nostr-sdk v0.44 (Python bindings for rust-nostr)
+
+nostr-sdk is the official Rust Nostr SDK with Python/Swift/Flutter bindings.
+Second most popular Nostr SDK after nostr-tools, powers native clients.
+
+Tests:
+  1. NIP-42 authentication (automatic_authentication)
+  2. Channel discovery (kind:40)
+  3. Channel metadata (kind:41)
+  4. Send channel message (kind:42 via EventBuilder.channel_msg)
+  5. Read messages (kind:42 fetch + round-trip verification)
