 Fix SPDX headers in all files 
I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.

v::subset([1, 2, 3])->assert([1, 2]);
// Validation passes successfully

v::subset([1, 2])->assert([1, 2, 3]);
// → `[1, 2, 3]` must be subset of `[1, 2]`
