feat(openfoam): a response parameter may follow a swept value

[dmitrat]

A force-coefficient response normalises by its reference speed (magUInf). When a study sweeps the inlet speed, a response that keeps magUInf 20 in every variant reports right coefficients at 20 m/s only. This lets a response parameter carry the study's tokens so the node gives it each variant's value.

OpenFOAM.Model 1.3.0

• FoamResponseRules: a parameter value may contain {{ocN}} tokens (each checked as a number until the variant supplies it).
• FoamTemplating.CheckResponseCoverage: a response token the study does not declare is a finding.

OpenFOAM 1.0.5

• FoamFunctionObjectWriter.Write(caseDirectory, request, substitutions) substitutes the variant's values into the response parameters, checks the real values with the same rules (a value that is not a plain dictionary value is refused and nothing is written), and names a token the variant gives no value.
• FoamCaseSession passes the task's substitutions.

Sweep 2.0.4

• The OpenFOAM family checks the response tokens when the study arrives, before any node sees it; carries Model 1.3.0.

Tests

• Rules, templating, writer and host tests for tokens, undeclared tokens, unsafe substituted values and leftovers.
• Kit oracle: pitzDaily twice with force coefficients on the lower wall — the reference speed written as 10, then taken from the variant as 20. OpenFOAM reports exactly a quarter of the first Cd (5.460085e-06 → 1.365021e-06 on the Windows kit).
• Locally: OpenFOAM 262 passed + 6 kit oracles, Sweep 77.
