LaminaPeek v0.1.0

Added

• Shulker Box preview: hovering a Shulker Box (any colour) in the player
  inventory, a Chest or an Ender Chest shows its contents as a 9×3 grid with
  item icons and stack counts. No keybind required.
• config.json (mods/LaminaPeek/config/) with shulker.enabled,
  shulker.showEmpty and shulker.disableVanillaContentsPreview.
• Vanilla's "contained items" hover-text lines are hidden for Shulker Boxes
  while the preview is enabled; the rest of the tooltip is unchanged.

Changed

• Target LeviLamina Client 26.51.3 (built against its SDK; --trace=y uses
  the RotatePolicy-based ll::io::FileSink introduced in 26.51.2).
