VSCode Extension

Rye would greatly benefit from a vscode extension that changes some behaviors that are currently in conflict with rye.

For instance it runs pip install for installing tools rather than rye add or rye install. Turns out that at least in parts this might either require patches directly to the python extension in vscode or some shims on the rye side to make it look like something that vscode already supports.

In addition for format and lint to work, the LSP would need to be proxied through (#593).
