initial commit — reusable splash screen library (0.1.0)

Configurable Figgle + Spectre.Console splash for .NET CLIs. Piecewise-
linear gradient across N hex stops, three tagline strategies (none /
random built-in / user-provided), lazy Figgle render + single-markup
emission (cold start <10 ms vs ~60 ms for the per-char precursor).

- src/NextIteration.SpectreConsole.Splash — library
- tests/ — 40 xUnit tests (gradient, colours, tagline, renderer,
  quotes, screen); all green
- demo/ — 5-scenario console app showing defaults, custom gradient,
  font swap, no tagline, solid colour
- CI builds + tests on ubuntu-latest (net10.0)
- Not published to NuGet; consume via git submodule + ProjectReference
