fix(nodedb-fts): bump jieba-rs to 0.9 to drop yanked core2 dependency

jieba-rs 0.8 pulled in include-flate → libflate → core2 0.4.0, which
was yanked from crates.io and caused CI to fail with a version-yanked
error during cargo clippy. jieba-rs 0.9 removes the libflate dependency
entirely, eliminating core2 from the transitive graph.
