1.0.2

Factorio 2.1 support with corrected science-pack filters, progress-window updates and existing-chest discovery. Cache and filter updates avoid repeating unchanged work, while native refill and the original production threshold remain intact. Legacy disabled-refill saves are restored.

Factorio 2.1.24 checks cover independent production thresholds, pack availability and native refill after packs are removed. Disable the original magic-science-chest before enabling the fork.
