chore: Bump version to v0.3.3

Co-Authored-By: Claude Opus 4.6 <[email protected]>

fix: disambiguate nostr_sdk Error types for Rust 1.94 compat

Rust 1.94 resolves the bare `Error` from `use nostr_sdk::prelude::*`
to `nostr::event::builder::Error` instead of `nostr_sdk::client::Error`,
breaking the inbox relay send functions. Use explicit types.
