Thread a seen-node-ID exclusion set from engram_compile() through to session_preload in handle_chat, preventing the same high-salience nodes (identity, recent memories) from appearing 2-3x in the system prompt. Changes: - Add id_in_seen(), add_to_seen(), engram_extract_ids() helpers that maintain a comma-delimited seen-ID accumulator (EL has no Set type) - In engram_compile(): after merging all topic/entity/recall pools, extract node IDs from merged_nodes and publish via state_set(engram_compile_seen_ids) - In handle_chat(): read seen_ids from state after engram_compile() returns, then check id_in_seen() before emitting each session_preload bullet (profile x3, work x2, project x2, summary x1 — all 8 candidate nodes guarded) Nodes already present in the compiled engram context are skipped in preload, eliminating 3000-3500 token repetition on first-message turns.
