Abort dev on app uninstall

[dmerand]

WHY are these changes introduced?

When a developer uninstalls an app while shopify app dev is running, the CLI continues trying to update the dev session, resulting in repeated error messages "The app isn't installed on the specified store" on every file change. This creates a confusing experience where the dev session appears to continue but is actually broken.

WHAT is this pull request doing?

This PR detects when an app has been uninstalled from the store and gracefully shuts down the dev session, similar to when a user presses 'q'.

When the uninstall error is detected:

1. Messages are displayed to the user
2. The dev session status is updated to show it's shutting down
3. The process exits cleanly with status 0

How to test your changes?

1. Start a dev session with shopify app dev
2. While dev is running, go to the store admin and uninstall the app
3. Make a file change to trigger a dev session update
4. Observe that the CLI now gracefully shuts down with clear messaging instead of showing repeated errors

Post-release steps

None required.

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.

If remote-error and unknown-error no longer do the same thing (so you need this extra if here), let's split them in different else-ifs, that way you don't need to check for remote-error twice
