feat: allow zero or multiple imported names in import statement

Make the `for` clause in import statements optional, and support comma-separated lists of imported names when present. This removes the previous restriction of exactly one imported variable per import statement.

- Refactor `import()` in compiler to handle optional `for` clause with loop over comma-separated names
- Update existing tests to use comma-separated imports and omit `for` clause where appropriate
- Add new tests: `inside_block`, `name_collision`, `no_variable`
