Translate code, comments and logs to English; English README; configurable paths and env varsHEADmain

Identifiers, docstrings, comments and console messages are now in English.
Narration, subtitles and on-screen text stay in Spanish (they are the video
content). The Blender <-> Godot physics protocol uses English keys and body
prefixes chosen to keep the original creation order, so cached simulations and
renders stay bit-identical. The old Spanish environment variable names are still
accepted.
