Support Unix shebang (#!) on first line of Lua files. The first line starting with #! is automatically stripped before tokenization, matching standard Lua behavior. Test added to lexer_test.exs. All tests passing (1085 tests, 0 failures)
More idiomatic Elixir - String.split handles Unicode properly and is what developers expect.
List.last() doesn't handle edge case of shebang-only file correctly. Case statement properly returns empty string when no code follows shebang.
