docs: sync living references + roadmap to call-script solved/executing

- tools-reference: run/play/sweep execute call-script (provider); trace/audio/gfx
  stay provider-less; corrected stale sweep numbers (284 exit/13 STEP-LIMIT) and the
  Godot --selftest description (synthetic vs headless, not vm0/186); added --scene.
- roadmap: call-script marked SOLVED (resolution + execution) throughout; no longer a
  'long pole'; per-game registry now automatic from SYS4INI.
- phase-a-slice-plan: SC0240 live-demonstration note.
