Breaking tripwire with shears does not consume durability

Summary

Breaking tripwire with shears correctly disarms it, but the shears do not lose durability in Survival or Adventure mode.

Current behavior

TripwireBlock::broken detects the held shears and sets disarmed = true, preventing the hooks from pulsing. It then stops at an explicit TODO:

// TODO: Deduct 1 durability from held shears (skip in Creative mode).

No held stack damage or inventory update is performed.

Vanilla behavior

Using shears to destroy and disarm tripwire costs one point of shears durability outside Creative mode. The special shears break path prevents the attached tripwire hooks from activating.

Reproduction

1. In Survival, connect tripwire between two hooks.
2. Note the held shears' durability.
3. Break one tripwire segment with the shears.

Pumpkin disarms the tripwire but leaves the shears unchanged. Vanilla consumes one durability.

Suggested fix

Damage the held shears by one in the disarm path using the normal item-damage helper, skip the cost for Creative players, and send the resulting held-slot/break update. Add Survival, Creative, and one-durability-remaining coverage while preserving the no-hook-pulse behavior.
