Pull request overview

Updates the Hardhat Node Test Runner plugin to align its build task invocation with the new Solidity splitTestsCompilation setting, and adds regression tests to ensure the correct noTests flag behavior.

Changes:

• Passes noTests to the build task based on hre.config.solidity.splitTestsCompilation.
• Adds node:test coverage verifying build invocation arguments for split vs unified compilation modes.
• Adds a test ensuring compilation is skipped when noCompile is set.
