Research system and datagen

26.1.2 introduces a research system that provides research nodes with multi-stage progression, numeric research values, toast notifications, and multiple trigger types for research ingress.

See Research System for full documentation.

Migration notes

Unlock conditions

Progression is now handled through the research system rather than standalone condition types. The old entry_read, entry_unlocked, and advancement condition types are replaced by research nodes and hooks:

• modonomicon:research_node_unlocked — gates behind a completed research node
• modonomicon:research_stage_completed — gates behind a specific stage of a research node

Advancement-based gating is modeled by creating a research fact that is granted when the advancement is earned, then gating the entry on a research node requiring that fact. See Research Scenarios for the pattern.

Entry and category conditions now largely go through the research system. The Unlock Conditions page lists the remaining non-research condition types (mod_loaded, category_has_visible_entries, logic combinators).
