Eric Wang a5407e03b2 feat(agent): align prompts and runtime with workflow@20261020
- archive workflow/20261020 export (diff vs 20261016: collection prompt
  only - state-decides-body rule, route when info complete)
- prompts: collection.md updated; 6 photo/confirm prompts archived with
  source nodeIds; render_prompt replaces {{$vars}} (Asia/Shanghai clock,
  person fields, explicit 'not provided' for missing prefills)
- llm: message history passed as user/assistant roles (chatNode history=50);
  optional LLM_TEMPERATURE; FakeLLMService supports history-aware responders
- collect: context via system supplement, raw user input as user message
  (Text Editor#2 parity), shared validated_reply (one call, one repair)
- welcome: Assigned Reply#3 original text, stored in dialogue history
- transitions: 2004 plate-confirm entries (2003->2004/2005, 2004->2005)
- verified: prompt files byte-identical to workflow JSON (parametrized test)

Eric Wang 1c6b1a513d feat(agent): LLM-powered collection node with welcome stage and session-scoped delete (assignment 4)
- prompts/collection.md: versioned collection system prompt extracted
  from workflow node yQaBxfrWjbRr with source/version/porting notes
- llm.py: LLMService protocol; FakeLLMService (scripted, records
  calls); OpenAILLMService (async, wait_for timeout with cancellation,
  retry only on timeout/429/connection, errors normalized)
- collect.py: run_collect reference impl - one LLM call produces
  state prefix + body, controlled repair (max 1 retry) for missing
  prefix or illegal stage proposal, whitelist guard, CollectReplyError
  without raw model content; dialogue history + confirmed fields
  injected into prompt so the model skips known info (作业4-5)
- fields.py / clock.py: three-state field candidates (unknown/
  candidate/confirmed), per-type validation (count not inferred from
  description, future time rejected), injectable Clock
- graph.py: welcome node - first message returns fixed 1001 greeting
  without LLM (mirrors workflow is_first_message -> Assigned Reply#3),
  route empty stage to welcome
- endpoints/delete_session: backend switch - langgraph clears graph
  checkpoint, fastgpt path unchanged
- config: AGENT_LLM_PROVIDER fake|openai with validation
- untrack .env (secrets), move template to root .env.example

Verified:
- pytest 103 passed; smoke turns 1/2/1
- Real LLM e2e: POST /chat multi-turn context works
- Golden eval collection_skip_known_info: 12/12 cases pass
- Golden eval no_false: 8/10 cases pass; 4 confirm/photo cases fail
  at final step - model routes on short reply '对' (prompt-adherence
  gap, photo/confirm stages are assignment 5 scope); recorded in
  evals/results/20261020-144856

Known limits: field extraction from model reply not wired (stub);
photo/confirm nodes still scaffold; clarify counting is approximate.
