support running in browsers (with emscripten)

need a frontend wrapper, lets see when i can finish it (i have no idea about frontend things)

TODOs

• running
• console output
• argument passing
• exit code display
• environment variables
• filesystem management
• CI builds
• deploy to Cloudflare pages
• add unit testing

im still trying to make this

currently web branch has staging support for running directly in desktop and mobile browsers

[affggh]

Is environment value available?

this wip port is now available on Cloudflare pages: https://magiskboot-build-wasm.pages.dev/

i will probably finish the file manager today EDIT: its generally working now (but with some minor issues, like currently the program runs in browser's main ui thread, which will cause freezes when doing heavy work, there is also some memory leaks...

so i guess i will keep this open until the bugs the support getting ready to merged into this main repo

so i guess i will keep this open until all these get resolved

the only reliable way seems to be using pthread or workers api, but im not familiar with js... (EDIT: currently using a hack with Asyncify to achieve real-time updating
