Adolf memory: migrate Cognee -> Hindsight + Kimi quota tooling

Memory migration (H1-H5, kb#73-77,84):
- hindsight service in openai/docker-compose.yml: LLM via Kimi (cognee-llm
  wrapper), multilingual GPU embeddings (bge-m3 via ollama), jina multilingual
  reranker; pg0 + model cache persisted
- openclaw.json/shared-mcp.json: mcp.servers cognee -> hindsight (bank "adolf")
- hindsight-openclaw-plugin: forced-hook memory (before_prompt_build recall +
  agent_end retain), replacing cognee's hook layer; cognify-sweep dropped
- verified live: Russian retain->recall, cross-session recall, bank isolation

Kimi quota (kb#62):
- adolf-llm/server.js: LLM-free GET /usage route (Kimi managed-usage API)
- quota-command-openclaw-plugin: /quota readout command

Cognee stack left running (decommission is H4/kb#76). Kimi-quota-footer
auto-append abandoned (streamed Matrix replies bypass outbound hooks).
