Problem: The magic globals `it`, `describe`, etc., are more trouble than they are worth. - Hooking into `after_each` requires `getfenv()` hacks. - They confuse luals/emmylua, because the top-level `.luarc.json` isn't merged with `test/.luarc.json` (apparently a luals limitation?) - They totally defeat discoverability because the user just has to "know" about the various magic symbols. So they harm DX, which means they serve no purpose at all. Solution: - Expose the test API from `testutil`, so tests can call `t.it()`, `t.describe()`, etc., in the conventional way. - Drop `getfenv()` hacks. - Drop the `setfenv()` injection in `load_chunk`. - Drop `test/_meta.lua`.
