RichardAHBot e470d8a70b fix: tighten jsontx_exact integer boundary at 2^53 ...

jsontx_exact: change the double boundary check from exclusive to inclusive
(d > max -> d >= max, d < -max -> d <= -max). Doubles cannot uniquely
represent odd integers at or above 2^53, so values like 2^53+1 silently
round to 2^53, corrupting the canonical form. The safe ceiling for
round-trip-exact integers is 2^53 - 1.

tests: add coverage for the 2^53 boundary (positive and negative sides,
and the silent rounding case).
