fix: let repeated notes play and require full test coverage - #20

Conversation
Paper applies the pressed hotbar slot after PlayerItemHeldEvent handlers run, so resetting to slot 9 left the server on the pressed slot and Paper then ignored the next press of the same key. Cancel the slot change after the reset so the server and client both stay on slot 9. Also skip slot changes other plugins cancel, reject instrument items that resolve to air, accept config case and drop leftovers in /instruments give, and resolve minecraft:-prefixed materials. Remove the per-player task that never displayed anything, and accessors and model-data helpers nothing calls. JaCoCo now fails verify below 100% instruction and branch coverage.

InstrumentListener.onPlayerHotbarChange so slot 9 (index 8), which is the reset
slot, cannot be mapped to a note; preserve the existing reset behavior.

Playing a note returns the player to slot 9, and pressing the selected slot sends no event, so a note mapped to slot 9 could not be played. Ignore slot 9 in the listener and warn at load when a config maps it. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>

Pressing the same hotbar key twice in a row played only one note on Paper 1.21.10. Paper applies the pressed slot after
PlayerItemHeldEventhandlers return (ServerGamePacketListenerImpl.handleSetCarriedItem), so the reset to slot 9 only reached the client. The server stayed on the pressed slot, and Paper skips the event when the pressed slot is already selected. The listener now cancels the slot change after the reset, so both sides stay on slot 9.Other fixes:
hotbar-sounds.9or9+sneakget a load warning, since those notes could never be played./instruments giveaccepts the names tab completion suggests, including config keys with capitals, and drops the item at the player's feet when the inventory is full.v.minecraft:<material>andmodeled(type=minecraft:<material>)resolve.Removed code that did nothing or was never called: the per-player repeating task (it only watched for its own cancellation),
onDisable(Paper already logs disabling),getInstance(),getItemResolver(),getManager(), and the unusedLegacyModelData.has,getand null handling. Nothing in the workspace calls the removed accessors; ActivityTF only usesInstrumentPlayEvent, which is unchanged.JaCoCo now fails
verifybelow 100% instruction and branch coverage. Test count goes from 7 to 52. MMOItems, ItemsAdder and Nexo are replaced in tests by small stand-in classes undersrc/test/javawith those plugins' package names. The listener tests reproduce Paper's slot handling;repeatsTheSameNotefails on the previous listener. Reverting each fix makes a named test fail. MockBukkit does not implement custom model data components, somodeled(...)model data is only tested with mocks.Validation:
