The IndexTTS-2 repo stores examples/emo_*.wav and examples/voice_*.wav
as Git LFS objects. v1 of our image cloned the repo without an LFS
pull, leaving those paths as ~130-byte pointer text files — unusable
for `docker cp` into /worktank/index-tts/{voices,emotions}/ as starter
references. (Caught when an emotion_voice="hate" call returned audio
that was actually the pointer text round-tripped through file IO.)
v2 adds git-lfs to the apt list, calls `git lfs install --system`
once, and `git lfs pull` after the checkout. Adds ~1-2 MB to the
image (the examples are small audio clips). INDEX_TTS_TAG bumped to
v2 to force a clean rebuild.
