Implement TypeExpression AST node to allow types to be used within
expressions, enabling the parsing of anonymous slice and array
initializers like `[]Type { ... }`.
- Register `[` as a prefix-style token (NUD) in the Pratt parser.
- Add `TypeExpression` node to AST and expression variants.
- Update `toDot` and `toString` visitors for AST visualization.
- Update frontend to open source files directly to fix issues at opening
paths.
