Summary: Building: - Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast. - Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var. - Grist-core continues to build using tsc. - Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned on, so that tsc accepts and enforces correct usage. - Client-side code is watched and bundled by webpack as before (using esbuild-loader) Code changes: - Imports must now follow ES6 semantics: `import * as X from ...` produces a module object; to import functions or class instances, use `import X from ...`. - Everything is now built with isolatedModules flag. Some exports were updated for it. Packages: - Upgraded browserify dependency, and related packages (used for the distribution-building step). - Building the distribution now uses esbuild's minification. babel-minify is no longer used. Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.
