fix(context-format): render nodes, replace _sel_N sentinels, fix hard_bell syntax, remove duplicates

- Add engram_render_ctx to convert raw engram JSON to human-readable bullets
- Wire build_system_prompt to call engram_render_ctx(ctx) so LLM sees prose not JSON
- Remove duplicate function definitions (chat_default_model, engram_score_node, old engram_compile_ranked) that were left in by the feature branch
- Fix }ory.el" corruption at join point between prepended functions and original file
- Fix missing closing } after hard_bell early return in handle_chat_agentic
