Captures the day-1 plugin + scripting contract for acdream:
C# plugins via collectible AssemblyLoadContext with a stable
IPluginHost API, Lua macros via a first-party Macros plugin that
embeds MoonSharp, and a four-stage packet pipeline for raw and
parsed traffic in both directions. Extends the phased MVP so
every core system is exposed through the plugin API in the same
commit that adds it.
