orchestrator/state.py
Adam Moussa ac7101f3df Add memory retriever node (Phase 2)
Plugs the orchestrator into Adam's existing memory store at
~/.claude/projects/-Users-adammoussa-Documents-repositories/memory/. Every
run starts with a top-3 retrieval pass that is then surfaced in the CLI
output and injected as system context into the router and downstream agent.

- retriever.py: load *.md memories (skipping the MEMORY.md index), embed
  with text-embedding-3-small, cache to .cache/embeddings.json keyed on
  file mtime. Cosine similarity, top-k=3 default. Reads only — never
  writes back to the memory store.
- state.py: add `retrieved: list[dict]` to OrchestratorState; relax to
  total=False to match LangGraph's partial-update semantics.
- graph.py: new retriever_node wired as START -> retriever -> router.
  router_node and connector_node now inject retrieved memories into their
  SystemMessage. Retrieval failures are caught and the run continues with
  empty memory context (logged).
- agents.py: make_agent_node injects retrieved memories into each agent's
  system prompt.
- run.py: prints `[retrieved: name1, name2, name3]` (or `[retrieved: none]`)
  before route/result for both --route-only and full-run modes, so bad
  retrieval is visible at a glance.
- .gitignore: add .cache/, .pytest_cache/, .ruff_cache/.

Validated: golden-set still 21/21 passing; smoke tests retrieve plausible
memories ("Send a Slack message to ops about the new exec-aide deploy" ->
project_exec_aide, feedback_exec_aide_vip_management, project_seahaven_slack_bot).
