refactor: replace UMD output with CJS and simplify ESM artifacts

Remove the duplicate .mjs ESM output and replace the UMD dist with a
dedicated CJS build. Remove the "browser" condition from the exports
map, which caused default imports to resolve as undefined in
browser-targeted resolvers such as Webpack 5 and Rollup (closes #38).
