Musashi Story v0.9.2 — Sheathed Weapon Presentation Hotfix

- Keeps the working left-click attack detection from v0.9.1.
- Rebuilds Katana, Nodachi, and Wakizashi idle geometry as truly sheathed weapons.
- Removes exposed blade geometry from the idle state.
- Aligns the scabbard directly with the hilt/guard instead of rendering it beside the blade.
- Left click still switches to the dedicated drawn model and uses Minecraft's native hand swing.
- Releasing attack returns the item to its sheathed state.
- No world reset is required.
