Rename all DiagCode enum variants in the lexer to use the STRUCT_ prefix to match the specification. This clarifies that these diagnostics relate to structural/lexical issues in PDF documents. Changes: - InvalidName -> StructInvalidName - InvalidHex -> StructInvalidHex - InvalidOctal -> StructInvalidOctal - InvalidStreamHeader -> StructInvalidStreamHeader - UnexpectedEof -> StructUnexpectedEof - UnterminatedString -> StructUnterminatedString The hex string lexer implementation was already correct, with proper handling of: - Hex digit pair decoding - Embedded whitespace (PDF spec 7.2.2) - Odd-length zero padding: <4> -> \x40 (dangling nibble is HIGH) - Invalid character diagnostics - Unterminated string diagnostics All 16 hex string tests pass, including critical tests for odd-length padding and error handling.
