Steven Ortega 0cb400c6ab feat(regions): add vendor shop regions for all remaining towns 
Extends vendor shop region coverage from the four initial towns
(Britain, Trinsic, Vesper, Minoc) to every remaining town that has
vendor spawns across all facets, completing issue #1052.

Adds 290 NoHousingRegion shop child-regions for 19 towns spanning
Trammel, Felucca, Ilshenar, Malas, Tokuno and TerMur: Jhelom, Cove,
Magincia, Moonglow, Nujel'm, Ocllo, Papua, Serpent's Hold, Skara Brae,
Wind, Yew, Buccaneer's Den, Delucia, Gargoyle City, Reg Volon, Luna,
Umbra, Zento and Royal City.

Regions are derived from the actual vendor spawn coordinates and follow
the existing curated 16-type shop vocabulary; co-located profession
clusters (e.g. Alchemist/Mage/Herbalist, Armorer/Weaponsmith, Cobbler/
Provisioner) fold into one shop region, matching how the first four
towns were authored. Jhelom resolves correctly as a town nested under
"Jhelom Islands".

Taverns and inns are intentionally excluded (already covered by the
existing NoLogoutDelay regions). Vendors that share a spawn point with
another shop type, sit inside an existing no-logout or gypsy-camp
sub-region, or fall outside any town region are omitted.

  • Check prerequisites (.NET SDK, native libraries)
  • Walk you through configuration and platform selection
  • Build and publish the server to the Distribution directory
  • Show deployment instructions for cross-compiled builds

Command Line

./publish.cmd [release|debug] [os] [arch]

Linux Prerequisites

Fedora, CentOS, RHEL, etc

dnf upgrade --refresh -y
# CentOS does not come with EPEL enabled
dnf install -y epel-release epel-next-release
dnf install -y findutils libicu libdeflate-devel zstd libargon2-devel liburing-devel

Ubuntu, Debian, etc

apt-get update -y
apt-get install -y libicu-dev libdeflate-dev zstd libargon2-dev liburing-dev

OSX Requirements

brew install icu4c libdeflate zstd argon2

Running the Server

  • Follow the publish instructions
  • The Distribution directory is portable — copy it to your production server for deployment
  • Run ModernUO.exe or dotnet ModernUO.dll from the Distribution directory
  • On first run, the server will prompt you to configure game data file locations
