pnpm package manager tool upgraded to version 9.1.1 in the emsdk image. Also it is deployed using corepack for better convenience

2. Reorganized image definition to make possible independent build of images for emscripten boost/openssl and NodeJS+npm preinstalled package set.

Updated set and versions of preconfigured TS specific packages, especially Typescript and PlayWright.

Changes to improve support for usecases when host user-id is different to docker-internal user-id (i.e. when container is spanwed from MacOS)

Added pnp package preinstallation step to cache large and rarely changing dependencies (like PlayWright)

Docker and script definitions for emscripten toolset (including precompiled boost openssl and sec256k1 libraries)
