Nova removes reaction filter, relaunches score sharing

Blueprint miners now search the full chemical space without reaction constraints starting tomorrow, expanding algorithm generalization requirements. Compound's score sharing system relaunches with improved logging, nanobody support, and a 100-block buffer; four atom types (Se, Na, Fe, Zn) banned starting epoch 22387.

• •Blueprint: reaction filter removed, full chemical space search enabled
• •Compound score sharing: live with per-validator logging and nanobody support
• •Buffer increased to 100 blocks for accessing previous epoch results
• •Four banned atom types in Compound starting epoch 22387
