Bug: Typo in adventure name hint causes user confusion

File: Solutions/CSharp/Program.cs, line 9

Problem

The help text shown to users lists "elodoria" as a valid adventure name, but the actual switch case handles "eldoria". Any user who types elodoria following the hint will hit the default case and see Unknown option: elodoria.

// Current (broken):
Console.WriteLine("Please specify which logic to run: Sample names include: algora, chamberofechoes, elodoria, lumoria, mythos, mythos-test, stonevale, tempora.");

// Should be:
Console.WriteLine("Please specify which logic to run: Sample names include: algora, chamberofechoes, eldoria, lumoria, mythos, mythos-test, stonevale, tempora.");

Fix

Change "elodoria" → "eldoria" in the help string on line 9 of Solutions/CSharp/Program.cs.

Impact

Low effort, high clarity — this is a beginner-facing repo and users following the printed instructions will get a confusing error.
