Remove bustub-hyperloglog-impl-001 from active selection + fix teleport instruction

bustub requires TAC-specific infrastructure (DinD, proprietary eval.py,
external server init) incompatible with our standard pipeline. Feature
suite drops to 22 tasks, matching the Neyman-optimal allocation.

Also fix bare $DEVICE_NAME shell variable in teleport instruction.md
(replace with <device-name> placeholder).
