chore: use rollup instead of tsup for a cleaner dist (#255)
* update tsup to 8.2.0 (no change to dist) * add rollup config to generate dist * fix browser build config * browser umd bundle sourcemap should be published * browser bundle is iife, not umd, despite folder name * rollup: don't use manualChunks to keep the config a tad simpler * prepack: use rollup instead of tsup * remove browser entrypoint from dist * remove comments in .js and .mjs outputs * remove src/browser.ts, use equivalent Rollup config * Restore original .npmignore * rollup config: rename umdBuildConfig to browserBuildConfig * rollup: use package.json#exports for esm entrypoints * chore: package.json * rollup config * sort * lint * prettier --------- Co-authored-by: Sojin Park <raon0211@toss.im>
