README references nonexistent scripts (train.py, train_model.py)

[Doomsbay]

The Organization tree and Training section use wrong filenames, and several important files are missing from the tree.

Wrong names

The README references two scripts that don't exist:

• L37 (Organization): lists train.py — should be train_gd.py
• L140 (Training command): shows train_model.py — should be train_gd.py

Following the Training instructions as written produces:

python3: can't open file 'scripts/train_model.py': [Errno 2] No such file or directory

Missing from org tree

• scripts/process_seqs.py — the inference entry point used in the Inference section
• scripts/fix_librhash.sh — referenced in MacOS install steps
• models/ — contains model and taxonomy files used in Usage examples

Suggested fix

1. Fix the org tree to use actual filenames (train_gd.py, process_seqs.py, fix_librhash.sh)
2. Fix the Training command at L140 from train_model.py to train_gd.py
3. Add models/ to the org tree
