Bitesize Reading Library V4.9.7 — Discover search parity

• Reading Library continues to prefer full skill/phrase and synonym matches.
• If no precise match is found, Discover offers a separate, explicitly labelled group of broader Catalogue Manager-style partial keyword results. These are not claimed to be verified matches for a curriculum skill.
• Live catalogue keyword import now combines top-level and nested metadata rather than allowing an empty top-level field to mask valid nested terms. Additional learning-objective and standard keyword fields are retained.
• All other features from V4.9.6 are preserved, including the bonus, YouTube page and newsletter.
