- Drop redundant `use anyhow::Context` inside has_any_faces (already
imported at the module level).
- Drop dead `.unwrap_or("?")` on bound faces — the vec is filtered to
is_some() so the fallback can never fire.
- Reorder the face_dao constructor param + initializer to match the
struct declaration (between tag_dao and knowledge_dao). Update both
state.rs call sites and populate_knowledge.rs to match.
- Hold face_dao lock once across the library-resolver loop instead of
reacquiring per iteration.
