Projektstruktur: game/-Package angelegt, README ergaenzt

Laufzeit-Code vom Dev-Werkzeug getrennt:
- game/: das eigentliche Spiel, startbar per `python -m game [--once]`.
  - formats.py  (war tools/kellogg_formats.py) -- Asset-Parser, Kern-Bibliothek
  - audio.py    (war tools/tfmx_audio.py)      -- TFMX-Musik-Wrapper
  - intro.py    (war tools/intro_sequence.py)  -- Boot-/Intro-Sequenz
  - tfmx_player/(war tools/tfmx_player/)        -- MIT-C-Renderer
  - __init__.py / __main__.py fuer `python -m game`
- tools/: nur noch Dev-Werkzeuge (dat_extract, pcc_to_png, render_assets),
  importieren jetzt aus game.formats.
- README.md: Ueberblick, Start, Struktur, Voraussetzungen, Rechtliches.
- .gitignore: tfmx_player-Binary-Pfad auf game/ nachgezogen.

Intro laeuft unveraendert (headless-Smoke-Test `python -m game --once` exit 0).
