Closes #235.

What: fechas pre-1970 correctas en vez de pánico — walk anual hacia atrás en epochDaysToIso, descomposición floor (@divFloor/@mod) en epochSecondsToIso.

  • src/parquet.zig solo: sin firmas, sin fatal; 1 unit test (7 asserts, incl. bisiesto).

Test:

  • days -1→1969-12-31, -366→1968-12-31; secs -1→1969-12-31 23:59:59; controles post-1970 intactos.
  • zig build unit-test y zig build test exit 0.
