feat: build the Rust binary via ext/extconf.rb, not bin/setup

gem install elelem-ratatui now builds the binary automatically (spec.extensions), matching elelem-llama's cmake precedent. Previously bin/setup ran cargo directly, which only worked for a cloned checkout. extconf.rb builds into ext/elelem/ratatui/native/, and Session::BINARY points there instead of rust/target/release. bin/setup now just runs bundle install + rake compile for local dev.
