0.1.2

Patch release focused on clearing static-analysis and security warnings so the
solution builds cleanly with warnings-as-errors. No public API or behavior changes.

Changed

• System.Text.Json bumped from 8.0.0 to 8.0.6, resolving the two high-severity
  advisories (GHSA-hh2w-p6rv-4g7w, GHSA-8g4q-xg66-9fp4) reported as NU1903.
• Version bumped to 0.1.2.

Fixed

• NU1903: System.Text.Json 8.0.0 → 8.0.6 (known high-severity vulnerabilities).
• CS0419: ambiguous XML doc crefs that collided with same-named members are
  disambiguated with the T: ID-prefix
  (Response → Dataset/Collection/Dimension; Dimension → Category).
• CS8602: nullable-returning navigation calls (Dimension(...), Data(...),
  Value) dereferenced in the test suite are now annotated with the null-forgiving
  operator, matching the convention already used elsewhere in the tests.
• xUnit2013: Assert.Equal(1, …Count) replaced with Assert.Single(...).
