evals: add 3 C API evals for cuopt-numerical-optimization-api-c skill

[rgsl888prabhu]

Adds 3 new evals to skills/cuopt-numerical-optimization-api-c/evals/evals.json (was 1, now 4), all grounded in skill-specific C API content from SKILL.md and references/examples.md.

📝 Walkthrough

Walkthrough

Three evaluation test cases are added to the cuOpt C API skills evaluation file. The changes cover parameter setter function identification, CSR constraint matrix representation, and quadratic programming restrictions in the cuOpt C API.

Changes

cuOpt C API Evaluation Coverage

Layer / File(s)	Summary
API evaluation cases skills/cuopt-numerical-optimization-api-c/evals/evals.json	Three evaluation items added: (1) identifying the correct parameter-setter function for float parameters like CUOPT_TIME_LIMIT and listing the three available functions by type; (2) specifying CSR array representation for a small 2-constraint/2-variable LP with explanation of array semantics; (3) documenting QP restrictions including integer QP unsupported status, minimization requirement, and continuous-variable requirement.
Benchmark metadata update skills/cuopt-numerical-optimization-api-c/BENCHMARK.md	Updated evaluation date, execution environment, dataset/task counts, added security signal, and refreshed result metrics and Tier 1 summary.
Skill-card and references skills/cuopt-numerical-optimization-api-c/skill-card.md	Reworded use-case to reference embedding LP/MILP/QP into C/C++; consolidated references, adjusted Skill Output metadata, added security signal, and updated evaluation results table.
Sigstore DSSE bundle skills/cuopt-numerical-optimization-api-c/skill.oms.sig	Replaced DSSE bundle payload digests and signature with updated SHA-256 digests and a new signature entry.
