"""Install-time initialization and integration precedence (T049, T050).

``specify bundle install`` into an uninitialized directory must scaffold a Spec
Kit project first (FR-012), choosing the integration by precedence (FR-013):
explicit ``--integration`` override → bundle-declared integration → default.
The end-to-end test runs fully offline against bundled assets.
