This change adds a batch runner for the Cosmos3 NIM examples, centralizes generator defaults in examples/settings.py, and updates the example scripts to use shared request-building helpers, output handling, and CLI overrides. It also adds offline tests and a request snapshot contract to catch drift between scripts and their generated requests, while documenting the full suite and runtime/profile checks in the README.

Thank you for this, @ak495867. A shared config, a batch runner and request-snapshot tests are useful ideas for the NIM examples.

We're closing this PR because it can no longer merge here. The NIM cookbook moved to NVIDIA/cosmos-framework (.agents/skills/cookbooks/cosmos3/nim/) and was removed from this repo in #384. Since then it has been updated to NIM 2.1.0 (cosmos-framework#296) and gained new examples (reasoner.py, streaming.py, policy_droid.py, inspect_profile.py), so the example scripts this PR refactors have changed.

If you'd like to continue, please open an issue on NVIDIA/cosmos-framework first, so the NIM cookbook owners can agree on the shape before you rebase about 3,000 lines. Splitting it would also make review much easier: the shared settings and helpers first, then the batch runner, then the tests.
