Context Management

[vanderstack]

For anyone new to the tool I wanted to point out one of the most valuable features which I've only recently discovered and is not yet documented. There are commands to save and load context file paths using the file .vscode/contexts.json. These can be used as context presets to quickly change what should be included when switching between different parts of the project you're working on and because they are saved as text in the json file its also easy to compose them by hand into new presets too.
