AIR CLI: always upload requirements.yaml on the run submit path

[riddhibhagwat-db]

Changes & Why

The AI Runtime launcher reads <func_dir>/requirements.yaml for every run. The Go CLI only uploaded it when a requirements file or inline dependencies were declared, so a run with no dependencies (e.g. a plain command) shipped no requirements.yaml and failed at launch with RUN_EXECUTION_ERROR. Jobs then retried, and the retries surfaced an unrelated PrincipalContext propagation error, masking the real cause.

Always upload requirements.yaml: the declared file, a synthesized doc from inline dependencies, or an empty doc when neither is set. This matches the Python CLI, which synthesizes an empty requirements.yaml for the AI Runtime path.

Tests

• added 3 unit tests in experimental/air/cmd/runupload_test.go for each of the three branches as described above
• Manual verification: see screenshot below; was able to acquire gpu and run with same quickstart payload
