feat(charka): charka-lexer — tokenizador de COBOL

Browse Source 
Primera etapa del transpilador COBOL→Rust (Fase D del plan macro):
texto COBOL → secuencia de Token. Lexer deliberadamente tonto (emite
Word para todo identificador, la clasificación es del parser). Tokens
Word/Number/String/Period/Symbol con línea+columna; soporta formato
fijo (tarjeta de 80 columnas) y libre; comentarios, comillas dobladas,
operadores de 1 y 2 caracteres. LexError tipado. 17 tests; clippy
limpio. Limitación v1: sin continuación de literales entre líneas.
