== HypergridLinker ==

HypergridLinker handles linking to remote grids. It is created by GridService if HypergridLinker = true in config.

Key behaviours:

* LinkRegion() contacts the remote grid's Gatekeeper via GatekeeperServiceConnector to obtain the remote region's UUID, handle, size, and map image
* Linked regions are stored in the regions table with Hyperlink + NoDirectLogin + RegionOnline flags
* IsLocalGrid() checks whether a URI belongs to this grid -- prevents hyperlinking to local regions
* TryUnlinkRegion() removes the hyperlink record from the database
* Map tiles for linked regions are stored in the MapTileDirectory (default: maptiles/)
* The 4096-region distance check is disabled in current code -- distance enforcement moved to EntityTransferModule

HypergridLinker is disabled if HyperGrid config section is missing -- throws on construction.
