SonarQube Analysis / sonarqube (pull_request) Successful in 3m41s
chore(sonar): clear residual test-file smells (NUnit2046, NUnit2045, CS8604)
- **NUnit2046 (15)**: extend the prior regex sweep to also catch the
  `Is.GreaterThan(n)` / `Is.GreaterThanOrEqualTo(n)` variants on
  `.Count` and `.Length` — the previous pass only handled `Is.EqualTo`.
  Affects PG/Snowflake `QueryBreakdownTests`, PG `StatementReaderTests`,
  `LinqToSql` `QueryComparatorTests` / `QueryValidatorTests`,
  `Markdown.Tests` `ExpressionGeneratorTests` /
  `QueryBreakdownGeneratorTests`, and `JsonTokenReaderTests`.

- **CS8604 (8)**: `merged[someKey]` access inside `Assert.Multiple(() =>
  { ... })` lambdas where `someKey` is `string?` from `FirstOrDefault`.
  The preceding `Assert.That(someKey, Is.Not.Null)` does not propagate
  null-narrowing into the lambda scope, so add `!` to the dictionary
  index. (Tests fail loud with a meaningful message if the key really
  is null, so this is safe.)

- **NUnit2045 (1)**: wrap a four-assert block in
  `JsonTokenReaderTests.cs:65-68` in `Assert.Multiple`. Mirrors the
  surrounding two `Assert.Multiple` groups in that method.

All 1180 tests stay green.
