v0.1.2: number-grammar digits are ASCII only + packaged README
Losslessness fix + packaged README (spec v3.5.2)
.NET's Regex matches \d in Unicode mode (\p{Nd}), so a value like 1.٥ (ASCII 1, ., then U+0665) was classified as number-shaped and quoted on encode, where the ASCII SDKs leave it bare: a byte-identity divergence across the fleet. (Decode was unaffected, since double.TryParse with InvariantCulture rejects non-ASCII digits.) The number grammar and numeric-like patterns now pin digits to ASCII [0-9].
Both packages (BlackwellSystems.Gcf and BlackwellSystems.Gcf.Cli) now ship the README on their NuGet page.
Verified against new conformance fixtures (scalar/029-031, decode/007) and the cross-SDK differential fuzz. Spec errata: gcf v3.5.2.
