Terminal Improvements

We have made multiple changes to how we run terminal commands in Amp:

Environment β€” Commands now run by default in the integrated VS Code terminal inheriting your shell environment including Python virtual environments and direnv configuration.

Interactivity β€” Use the new "View in Terminal" button to interact with commands that require stdin, or the new "Detach" button to let the command continue running in the background.

Output β€” Progress bars with ANSI escape codes now render beautifully in the UI without eating up your context window, only the final output is presented to the model.
