Merge order: 1a → 1b → 1c → 1d → 2a → 2b → 3a → 3b → 3c, all into engine/hvr-replacement (no stacking). Each branch still contains the commits of the earlier steps, so after the earlier PR is merged the diff of this one shrinks to its own step. Plan: Docs/HVR-replacement/.

Description

Phase 3c: chests and NPC loot on the Xri backend (needs 3b). Completes Phase 3. Also adds Docs/HVR-replacement/found-bugs.md.

• VrChestSlots (chest content, slots fitted to the chest mesh, silent bulk spawn) on oCMobContainer; separate Xri slot children and a DropZone so dropping an item into the open chest stores it.
• Interim chest lid VrChestLidToggle (grip = open/close, supports lock picking) until Phase 4's physical hinge.
• VRNpcLoot uses VR Socket Slot on Xri; taking an item moves it to the player, equipped items show [E].
• IVrHinge.IsActive/VrHinges.FindActive; door/container code tolerates a missing hinge. Opening a chest on Hvr no longer plays a burst of weapon sounds.
• Slots keep their items when a chest closes.

To test

• - Hvr: open a chest by physics, take/put items, loot an NPC; unchanged (apart from silent opening).
• - Xri: grip the chest lid → opens, items appear small in the slots; take one; drop one into the chest; close/reopen → same items, none doubled.
• - Xri: loot a dead NPC → equipped weapon marked [E]; taking it removes its mesh from the corpse; closing removes the slots.
• - Xri: lock-pick a locked chest (untested).
• Not tested: sounds, save → load, invalid ring on a full slot.
• Known: > 12 items need pagination (logged as before); taking items doesn't change the saved chest contents; grabbing runtime-spawned chest items logs a culling error (found-bugs.md).

Test on (delete if irrelevant)

• PCVR
• Mobile VR (Quest/Pico)

Locks not tested but Chest. Works as expected here.

Lockpicking tested. Works too.
