fix(nodedb-fts): drop jieba-rs dep to unblock cargo publish

jieba-rs pulls include-flate → libflate → core2 0.4.0, which is yanked
on crates.io. The workspace [patch.crates-io] bypassed this locally but
was ignored by cargo publish's isolated packaging resolve, so releases
kept failing on nodedb-fts.

Drop jieba-rs entirely and let lang-zh fall back to CJK bigram
segmentation (the same path used when the feature is disabled). The
feature flag is retained as a no-op so downstream configs keep
compiling. Can be restored when the upstream flate chain moves off
yanked core2.
