EmakiStrengthen | Equipment Star Strengthening

Added

• Provider-based equipment, affix, and gem enhancement targets; affix progression; multi-track pity; item mastery; and explicit cost-consumption timing.

Optimised

• New target transactions use snapshots, validation, compensation-aware results, persistent pity state, and retry diagnostics.

Breaking Changes

• Migrate legacy match/source_ids conditions and related star-recipe fields to the current matcher/target schema; migrate historical enhancement PDC keys through CoreLib.

Upgrade Notes

• Back up configuration, player items, and pity state; preview the legacy conversion; then test every target mode, cost boundary, failure/refund path, pity track, mastery flow, branch, and optional integration.
