Add Linux-native cTrader cBot build/run scaffold

Build cBots in C# and compile them to .algo entirely on Linux via the
official cTrader.Automate NuGet package + 'dotnet build' — no Windows and
no cTrader desktop app. Run/backtest headless through Spotware's official
cTrader console Docker image.

Includes:
- src/SampleCBot: example SMA-crossover cBot (SDK-style net6.0 class library)
- scripts/install-dotnet.sh: root-free local .NET SDK install (~/.dotnet)
- scripts/build.sh: dotnet build -> dist/<ProjectName>.algo, with a workaround
  for cTrader.Automate naming the .algo after the project's parent folder
- scripts/run-console.sh: wrapper over ghcr.io/spotware/ctrader-console
- docs/research-findings.md: sourced research; .algo verified as a proprietary
  'algo'-magic container (not a ZIP); build verified end to end on Linux

+# Run / backtest a compiled .algo headlessly using Spotware's OFFICIAL cTrader CLI
+# Docker image — no cTrader desktop GUI, no Windows. Available since cTrader 5.4.
+#
+# This is a thin wrapper: it mounts your built .algo files (dist/) into the
+# container at /mnt/Robots and forwards all arguments to the cTrader console.
+#
+# Discover the exact subcommands/flags for your image version first:
+#
+#   ./scripts/run-console.sh --help
+#
+# Then backtest or run, e.g. (flag names follow the container's --help output):
+#
+#   ./scripts/run-console.sh backtest --robot SmaCrossOverBot.algo \
+#       --symbol EURUSD --period h1 --start 2024-01-01 --end 2024-06-01 \
+#       --balance 10000
+#
+# Live trading additionally needs cTrader ID credentials passed to the console.
