feat: replace AST matcher with simpler and robust logic

[twada]

Replace AST matcher with simpler and robust logic since AST deep-equality introduces extra dependencies.

BREAKING CHANGE:

Configuration options are simplified. Patterns are decomposed into variables and modules.

+ {
+   variables: [
+     'assert'
+   ],
+   modules: [
+     'assert',
+     'power-assert',
+     'node:assert'
+   ]
+ }
