Honor ChainsToThis for zero-argument constructor delegation

[Copilot]

ConstructorTemplate previously emitted an initializer only when BaseParameters was non-empty, making ChainsToThis = true ineffective for zero-argument delegation. As a result, intended : this() chains were silently dropped and constructors fell back to implicit : base().

• Initializer emission logic

  • Updated ConstructorTemplate.WriteInitialiserTo to emit an initializer when ChainsToThis is true, even if BaseParameters is empty.
  • Preserves existing behavior for base initializers when no parameters are supplied.

• API contract/docs alignment

  • Clarified XML docs on BaseParameters and ChainsToThis to explicitly describe empty-argument behavior and : this() emission.

• Coverage for missing case

  • Added a focused template rendering test for ChainsToThis = true with empty BaseParameters, asserting : this() is produced.

new ConstructorTemplate
{
    Name = "Widget",
    Keywords = { "public" },
    Parameters = { new ParameterTemplate { Type = "int", Name = "count" } },
    ChainsToThis = true,
}

Now renders:

public Widget(int count)
    : this() { }

• Fixes ConstructorTemplate.ChainsToThis is silently ignored for a zero-argument : this() #96
