Franknoirot/adhoc/improve e2e (#6265)

* fix: increasing timeout to reduce failures..?

* fix: removing debugging code

* Remove unnecessary pixel color check

* Only close the command palette on disconnection events

This code closes the palette on *any* network event, including it
getting established. This made tests like "Create a few projects using
the default project name" unreliable.

Also adds a block comment about how we should do something more
sophisticated than bail out in the future.

* Show a toast to explain why the user just lost their command flow

* Remove unnecessary click in test. `fill` focuses already

* Oop don't spam this disconnection toast if the palette isn't open

Honoring exhausting hook dependency checks

* Skip circle snapshot test, it's being weird

* Disable the export button if engine connection is unavailable

* Refactor useDemoCode to hopefully be more reliable

* allow weak connections to receive demo code

* revert Refactor useDemoCode to hopefully be more reliable
