Task: #132
PR: #142
Feature: HUD #98
Shows a short prompt when the player is in range of a door, dungeon exit, or pick-up item. The E key still fires interact and itemPickup on KeyboardPlayerInputComponent. The prompt lives on the player so it survives room changes.

- Door:
Press E — Next room(bookshelf:Press E — Enter dungeon). - Blocked exit: same HUD slot (e.g.
Defeat all enemies first.). - Item:
Press E — Pick up <name>. Item wins if both are in range. - Leave range or finish pickup: prompt hides.
