Some bug fixes, QOL changes!

Changelog

• Follow after taming — Newly tamed blocklings switch to Follow and sync correctly (GUI no longer stuck on Wander).
• Creative spawn HP — Creative-tab blocklings no longer spawn with wrong HP (e.g. 12/14). Packed blocklings still restore their saved health.
• Size-scaled health — Max HP scales with size as you grow them with food; full size = full adult HP.
• Size armour bonus — Growing grants a small armour bonus (up to +2 at full size).
• Type evolution — After Shift+food evolution, stats/HP refresh for the new type and size.
• Work tasks — Buying Novice Farmer / Mine / Woodcut unlocks the task type only; it is no longer auto-added to the task bar.
