GridPlacementHost | Grid Placement Docs

Host orchestrator for the Grid Building plugin. One Node, one _unhandled_input, one [PlacementServiceGroup]. The host owns infrastructure (input handler, mode machine) and a settings-driven service group; game-scoped [GridPlacementSettings] decide which domain services exist, and player-scoped [PlacementSession] state feeds them. The host also owns the session registry (split-screen) and intent dispatch.

Name	Kind	Summary
`grid_placement_bundle`	Property	Game-scoped settings.
`HostLifecycleEmitter`	Field	Lifecycle-result emission, attempt-id minting, and telemetry recording (see host_lifecycle_emitter.gd). Extracted to keep this hotspot under its line ceiling; owns the bus, the allocator, and the diagnostic recorder, so the public methods below stay thin delegates.
