Problem

scripts/convert_release_config_to_training.py has a shebang on line 16, after the SPDX header:

#!/usr/bin/env python3      <-- line 16, ineffective
r"""Convert nvidia/Alpamayo-R1-10B ...

A shebang only works as the very first line of a file. On line 16 it's just an inert comment the kernel never sees, so even chmod +x + ./script.py would not work as the line implies.

Fix

Two reasonable options existed:

1. Hoist the shebang to line 1 (and rearrange the SPDX block beneath it).
2. Delete the shebang.

I chose (2) because:

• The other three scripts in scripts/ (download_pai.py, curate_pai_samples.py, convert_cosmos_rl_checkpoint.py) have no shebang at all — verified by grep -n '^#!' scripts/*.py.
• The file is shipped without the executable bit (-rw-r--r--).
• The script's own usage block invokes it as python scripts/convert_release_config_to_training.py ..., never ./scripts/....

Dropping the line matches the dir convention, removes a misleading marker, and keeps the SPDX header at the canonical position (line 1).

Verification

After this PR, grep -n '^#!' scripts/*.py returns nothing across the entire scripts directory. The script continues to be invoked exactly as documented.
