"""语义词典：condition/grant kind -> 真实 ID/形态。外置 ir_dictionary.json，

编译器与（M5）Web 后端共读。新增查表类 kind 只改 JSON，零代码改动。

form 决定 grant 编译串形态：

money -> "{id},{value}" （银两；正给负扣）
|

item -> "{item},{value}" （道具，item 由 grant 指定 drop_item_data ID）
|
||
friend -> "{target},{id},{value}" （友好度，需 target NPC slot）
|

join -> roleActionCode "{code}={target}"（入门，需 target）
