fix: download artifacts to temp directory to avoid naming conflict (#221)

The download-artifact action creates directories named after each artifact.
When downloading to bin/, this caused conflicts because the artifact directory
names matched the binary names (e.g., bin/agent-browser-darwin-arm64/agent-browser-darwin-arm64).

Fix by downloading to artifacts/ first, then using find to move the binaries to bin/.
