- Taxonomy sync keeps fig-/feat- by slug (hyphen), not name; HTML-unescape names
- Review: remove AI assist labels; Features picker for feat-*; derive fig_tag_ids
  from Figure term names (casefold match, no bridges); decodeName on display
- Unit tests for scoped_tags, fig match, Review UI contract; docs slug wording
