LHDF Shop - Smurfs

# LHDF Shop - Smurfs Connects the Smurfs Base Building System (SBB) to LHDF Shop: building plans, kits and breaching charges for sale, no-build zones, and a fix for SBB's periodic server freezes. Part of the Lost Hope Dynamic Framework (LHDF), built for the Lost Hope Survival server. The mod adds a "Building supplies" category, shop type and trader to LHDF Shop. A Game Master places no-build zones where SBB refuses every placement. SBB normally searches the whole map for its build pieces every five minutes, which freezes the server for several seconds; this mod keeps a list of SBB pieces and territory computers instead. SBB's own options are set in a JSON file. ## Features - 18 SBB items for LHDF Shop: - 13 plans: territory claim ($2,500), floor, wall, window, door frame, ramp, roof ($150), half wall ($100), door ($300), gate ($600), storage box ($800), safe ($1,500), valuable safe ($3,000). - 3 kits (at most 5 per trade): tier 2 upgrade kit ($1,500), tier 3 upgrade kit ($3,000), base repair kit ($800). - 2 breaching charges (at most 2 per trade), restricted and sold only by the Black market: homemade ($4,000), military ($9,000). - Category and shop type "Building supplies". Any trader can sell plans once its assortment includes the category. - Base building trader (Game Master placeable): construction worker outfit, cannot be hurt, stands still, map marker on. - No-build zone (Game Master placeable, Systems): circle (default radius 50 m) or rectangle. Inside, every SBB placement (plans, upgrade and repair kits, territory claim) is refused with SBB's hint "Building is not allowed in this area" and the plan is kept. Purple border while a Game Master edits. Shape and size are set in the Game Master "LHDF" tab of the zone and saved. - SBB registry: territory cache rebuild, territory decay, offline raid protection checks and SBB's first save walk a list of SBB entities instead of querying the whole map. - SBB's options in `ShopSmurfs.json` instead of Workbench...
