feat(lang): module NAME uses A, B - a module reaches only the modules it names

A reference from a module that declares uses into a module it does not
name is refused, exported or not, naming the use and the fix. A module
with no uses clause keeps the old rule; a package's module is always
usable; a friend is not held to it; a cycle in the declared graph is
refused; LUDIC_VIS_REPORT=1 lists the violations as uses: lines. Reseed.

+**`module fishing uses base, data` - a module declares what it may reach, and the compiler holds it
+to that.** A reference from a module that says `uses` into a module it does not name is refused,
+exported or not, with the use and the fix in the message ("fishing uses items.inv_add (...): add
+'uses items' to fishing's module line, or take it through a port"). A module with no `uses` keeps
+the old rule, a package's module is always usable, a friend is not held to it, a cycle in the
+declared graph is refused, and `LUDIC_VIS_REPORT=1` lists the violations as `uses:` lines.
