fix: add lexError function and fix line counting for unterminated block comments

Browse Source 
Add a dedicated lexError function that marks compilation as failed and formats
error messages consistently with a trailing newline. Move line counting from
readRawToken into nextChar so that newlines are tracked during all lexer phases,
including block comment scanning. Replace the TODO placeholder in
skipBlockComment with a proper lexError call for unterminated block comments,
and add test cases for unterminated block and nested block comments.
