Move core-v2 tests into packages/core-v2/tests

Tests no longer sit next to the implementation. They import the package
through ../src, the root tsconfig still type-checks them, and the
package build and declarations cover only src/.

 Pure helpers used by a class (for example `matchesStart`, `stepSpring`, or
 `composeNodeStyle`) are module-level `export const`s that the class calls, so
 they can be tested directly without widening the class's interface.
