BAS: Import code and other functions on Get started page are not working anymore in the new dev space

Nothing is working in BAS anymore - no project creation from template, not via import:

Reproduce the failure in a new BAS dev space, starting with the missing sapbas.importProject command and the extension-installation errors shown in the report. Inspect the extension entry points related to project import, template creation, and yeomanUI._notifyGeneratorsChange, along with the Copilot SDK dependency path. Done means project creation and import work without missing-command or incomplete-extension errors.
