platformio/platformio-vscode-ide ? reverse-engineered prompt

Build me a VS Code extension for embedded development like PlatformIO IDE.

I want it to help people create, build, upload, debug, and test microcontroller projects from inside VS Code, without having to juggle a bunch of separate tools. It should support common embedded workflows like code completion, linting, unit testing, serial monitor, firmware file browsing, memory inspection, and a built in terminal for PlatformIO commands.

Please make it feel polished and easy to use, with support for multiple projects, light and dark themes, and a clean sidebar or panels where users can manage their boards, environments, and devices. It should work across the major embedded platforms and frameworks that PlatformIO supports, and be focused on a smooth developer experience for beginners and experienced users alike.

If anything needs current docs or setup details, look them up online first.
