feat(app): wire plugin host, ship smoke plugin, log lifecycle

Browse source 
Phase 1 MVP end-to-end. Program.cs initializes Serilog, builds an
AppPluginHost that hands plugins a SerilogAdapter (IPluginLogger),
discovers plugins from the App's output plugins/ dir, loads each via
PluginLoader, calls Enable on all of them before opening the GameWindow,
and calls Disable in a finally block on shutdown.

AcDream.Plugins.Smoke is a new first-party plugin that logs through
the host during Initialize / Enable / Disable. Its csproj references
the abstractions with Private=false + ExcludeAssets=runtime to avoid
shipping a second copy of AcDream.Plugin.Abstractions.dll (which would
break ALC type identity). An MSBuild Target on the App project copies
the plugin DLL into plugins/AcDream.Plugins.Smoke/ and writes the
plugin.json manifest next to it.

Smoke verified against real dats. Console output observed:
  [INF] scanning plugins in ...\plugins
  [INF] smoke plugin initialized
  [INF] loaded plugin acdream.smoke (Smoke Plugin)
  [INF] smoke plugin enabled
  loaded landblock 0xA9B4FFFF
  <window renders terrain>
  [INF] smoke plugin disabled  (on shutdown)

Phase 1 done.
