Adds a self-check item to the AskUserQuestion preamble forbidding `\u`-
escape encoding of non-ASCII characters (CJK, accents) in AskUserQuestion
fields. The tool parameter pipe is UTF-8 native and passes characters
through unchanged; manually escaping requires recalling each codepoint
from training, which models get wrong on long CJK strings — the user
sees `管理工具` rendered as `3用箱` when the model emits the wrong
codepoint thinking it has the right one.
Long ≠ escape. Keep characters literal. Generated SKILL.md files for
all 36 skills that consume the preamble get regenerated in the next
commit.
