Wire: write doubles and floats with .NET Framework's round-trip digits

Browse source 
The original ran Newtonsoft.Json on .NET Framework, whose "R" format writes
15 significant digits when they read back exactly and 17 otherwise (floats: 7,
else 9). Modern .NET writes the shortest round trip instead, so a value like
-0.066666670143604279 came out as -0.06666667014360428: equal when parsed,
different bytes. Every frame now goes through a converter that repeats the
Framework rule, with Newtonsoft's '.0' suffix and non-finite handling kept.
Goldens that encoded the modern digits are corrected.
