feat(D-01/E): BuiltInLockComponent for organic items (E2)

- New BuiltInLockComponent: blocksUnequip() returns true (permanent lock)
- ComponentType: add BUILT_IN_LOCK enum value
- 8 organic item JSONs updated (slime, vine, web, tape variants)
- DataDrivenBondageItem: add hasBuiltInLock() static helper
