inputx-wubi-data 1.6.0

Embedded Wubi 86 IDFv1 dict blob + IdfReader OnceLock + Layer-from-EntryFlags helper for the inputx-wubi engine. Pure data + stateless lookup helpers (no application glue, no per-session state); successor to inputx-wubi-cement under the v1.5 D11 taxonomy correction (cement = application source, not a published crate).
