Hojun-Cho 07e57ff9a6 lib/strconv: decimal arbitrary-precision arithmetic (#106 fold-3) ...

Port ref/hare/strconv/decimal.ha (~202 LOC Hare) → 314 LOC
lib/strconv/decimal.ww — decimal struct + 11 fns (trim,
decimal_shift, leftshift, leftshift_newdigits, rightshift, round,
decimal_round, helpers). 1:1 mechanical Hare-fidelity with 8
documented spelling-divergences. Shared engine for stof (fold-4) +
ftos (fold-5). Built atop 5 wwstage cgen prereqs
(#131/#133-expanded/#134/#135/#138) that closed gate-blind silent
miscompiles surfaced by the port. Test 922_decimal_run +
lib/strconv/test/decimaltest.ww (6 @test fns covering all 11 impl
fns).
