📝 WalkthroughWalkthroughThis change adds named Boolean constraints to DSE test definitions. It validates and evaluates constraints against test context, applies them during DSE run generation and CloudAIGym steps before cache lookup, and documents the expression syntax.

Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Feature Merge Risk: 🔵 Low · up to Scalar configurations that violate a declared constraint may still reach Slurm, while DSE-grid and CloudAIGym paths are checked.

- a person should be able to use entire test definition. e.g.
vllmandsglangdeclare additional parent TDef properties besides cmd_args - also this structure doesn't correspond to a certain cloudai structure (TestRun, TestDefinition) but establishes its own model. I'd really like to see it reuses an existing one without hardcoded list of key (so that it's always up-to-date with our features)

I'm still not sure DSE term should be used in the public repo, I remember got questioned about it by our product manager (with no follow ups though)
Safer to call it sweep constraints

models is for models :) I think we should move it into src/cloudai/configurator as it's sweeping-related
