FRITZ'S RPG: BLACK CROWN 0.10.7 - TITLE AND SHELL FIX TEST

1. Replace all older Fritz's RPG JARs with this 0.10.7 JAR.
2. Build the forge with:
   /function fritzsrpg:structures/place_ruined_forge
3. Walk through the complete dungeon and check the roof, outer side walls and reward chamber for open holes.
4. Enter the boss chamber. The large title should now only display DURNAN, with the smaller subtitle The Ashen Smith awakens.
5. Confirm the boss doorway closes behind the player and reopens after Durnan dies.
6. Confirm all four side-room passages and the post-boss reward chamber remain accessible.
