fix: move template scaffolding after state transition in init

Template installer creates dist/ directories with .gitkeep files,
which has_build_artifacts detects as Built state. Moving install_all
after execute_transition(Initialize) prevents discover_state from
seeing dist/server/ and rejecting the Built -> Configured transition.
