Drop version suffixes from Blender source filenames

Rename the Blender working files to plain role names, dropping the version
noise: bull_v11 -> bull, matador_v03 -> matador, publik_mees_v01 ->
publik_mees, and collapse anim_bull2 into anim_bull (identical rig, newer
save kept; older duplicate dropped). Repoint create_matador_anims.py (blend
input + fbx export name), render_anim_preview.py and CLAUDE.md at the new
names.

The anim_* and sword files link the model blends as Blender libraries
(//bull_v11.blend, //matador_v03.blend, //publik_mees_v01.blend), so those
links need repointing once in Blender. The game is unaffected — it ships the
exported fbx/glb, not the .blend sources (art/blender/ is Godot-ignored).
