A GameFlow coordinator node (new main_scene) owns the Title → Creation →
Shell sequence in one file: instantiate → inject → add_child, reusing the
existing injection seam that change_scene_to_file cannot. Title becomes
emit-only; the shell gains injected_log/injected_state seams and stops
self-seeding on the real path (seed stays as the F6 fallback), so the
created character's vitals, location, and opening narration are real.
The ⛨ saga constraint is honored structurally: _show_creation and
_start_campaign are separate, so the fourth entry path is an added arm,
not surgery on existing edges.
