Handy Trader

Breaking

• Mod ID renamed from handytraders to handytrader to match the rest of the Handy series convention (singular). Existing config (config/handytraders.json) and per-villager favorites (config/handytraders-favorites.json) are migrated automatically on first launch — no settings or favorites lost.
• Internal package moved from net.rezanmb.handytraders to dev.handy.mods.handytrader. No user-facing impact unless another mod was depending on internal classes.

Changes

• Trade-identity hash upgraded from 32-bit hashCode to 64-bit truncated SHA-1. Eliminates the silent collision risk where two distinct trades on the same villager could star/unstar each other. Existing favorites are rewritten to the new format the first time you reopen each villager — no manual reset needed, but villagers you never revisit stay on the old format.
• Mod is now declared client-only (environment: "client"). Dedicated servers no longer load the jar; the mod was already client-only in behavior, this just makes it explicit.
• Favorites file write moved off the render thread so toggling a bookmark on a slow disk no longer stalls the frame.
• Config persistence rebuilt on YACL ConfigClassHandler (matches the rest of the Handy suite). On-disk JSON shape is unchanged; users without YACL installed still run on defaults.

Internal

• Cleanup wave aligned this mod with the rest of the suite — JAVA_25 mixin compatibility level, full @At descriptors, named bookmark color palette, narrowed exception handlers, and a CI release workflow that no longer fails on prerelease tags.
