fix(di): use factory lambdas for internal-ctor services

Browse Source 
C3 bootstrap throws "A suitable constructor for type
HellionChat.Ipc.ExtraChat could not be located" because
Microsoft.Extensions.DependencyInjection's ActivatorUtilities only
binds to PUBLIC constructors via reflection. ExtraChat is a public
class with an internal ctor; Commands and StatusBar are internal
classes whose implicit default ctor inherits class accessibility
(internal); every IHostedService adapter is `internal sealed class
X(deps)` with a primary ctor that is also internal.

The fix routes all eight singletons and all seven hosted-service
adapters through factory lambdas. `new T(...)` inside the
PluginHostFactory namespace sees the internal surface, so the
container never has to reflect over internal ctors.
