Chest Searching

First public release.

What's in it

• Item search on a hotkey (G, rebindable). Every item in the game, filtered as you type on both the display name and the registry id.
• Search radius slider, 8–64 blocks, saved to config/chestsearch.json.
• Server-side scan over the block entities of loaded chunks, so any container type is matched — including ones added by other mods. Nearest 512 results are returned.
• Green highlight cages that stay visible through any amount of terrain, drawn as a single clean outline whose corners meet seamlessly, dimming and brightening on a shared phase so every container pulses in unison. 30 seconds by default, fading out over the last three.
• Double chests draw as one rectangle spanning both halves and count as a single container, rather than two cubes with a seam between them.
• Action-bar feedback for both hits and misses.
• Unopened structure loot is skipped, so dungeon and shipwreck chests are never pre-rolled.
• On a server without the mod, the picker opens and says so rather than silently doing nothing.

Known limits

• Items inside a shulker box that is itself sitting in a chest aren't found yet.
• Matching is by item type and ignores NBT.
