fix(recall): resolve session-start-recall code review issues

- Fix Issue 6 (affective duplication): engram_compile no longer appends
  the bell node JSON to its return value; it only caches it via state.
  engram_compile_multi now appends the cached bell node exactly once after
  all compile calls complete, preventing N copies when multiple seeds are
  used. Dharma room handlers updated to read and append the cached bell node
  explicitly after their single engram_compile call.

- Fix engram_compile_ranked: replace _sel_N JSON sentinel injection with a
  clean |N| pipe-delimited index string. The old approach mutated node JSON
  objects with bookkeeping fields that leaked into the LLM context; the new
  approach tracks selected indices externally and leaves node data untouched.
  Score threshold lowered from 25 to 15 to include moderately-relevant nodes.

- Add engram_render_node / engram_render_nodes / engram_render_ctx: convert
  raw engram JSON arrays/objects into human-readable "- [TYPE age sal] content"
  bullet lines before injecting into the system prompt. build_system_prompt
  now calls engram_render_ctx so the LLM receives prose rather than opaque
  JSON field blobs.

- Fix missing closing brace in handle_chat_agentic hard_bell early-return
  block that left subsequent code dangling outside the conditional.
