Fixes age validation errors caused by the LLM not knowing the current date.
Changes:
- prompts.py: inject date.today() at the top of both system prompts so the
LLM can accurately calculate a child's age from their date of birth
- llm.py: add optional thinking_budget parameter to complete(); when set,
passes thinking={"type": "enabled", "budget_tokens": N} to litellm and
raises max_tokens to thinking_budget + 4096 (Anthropic models only)
- config.py: add thinking_budget field, read from THINKING_BUDGET env var
- .env.example: document the THINKING_BUDGET option
- core.py: pass thinking_budget through to llm.complete()
- main.py: pass thinking_budget when constructing EmailAgent
- chat_app.py: switch from stream_complete to asyncio.to_thread(complete)
so extended thinking works and so only the reply field is shown to
the parent (not the raw JSON wrapper)
To enable extended thinking set THINKING_BUDGET=8000 in .env.

Drops the src/providers/ package (base class, AnthropicProvider,
OpenAIProvider, factory) in favour of a single src/llm.py that calls
litellm.completion() directly. litellm handles provider routing,
authentication, and SDK differences for 100+ providers without any
code we need to maintain.
Changes:
- Delete src/providers/ entirely
- Add src/llm.py — one complete() function wrapping litellm
- src/agent/core.py: EmailAgent takes model: str instead of LLMProvider
- src/config.py: ai_provider + api key fields → single ai_model string
in litellm format (e.g. "anthropic/claude-opus-4-6")
- main.py: remove provider factory wiring; pass config.ai_model to agent
- .env.example: simplify AI section, show litellm model string examples
- pyproject.toml: replace anthropic + openai deps with litellm>=1.0.0
- uv.lock: regenerated

Closes the gap where parents sending a new email (instead of replying)
would lose their registration progress. All changes follow the
email-based-conversation-matching OpenSpec change.
Key changes
-----------
storage/json_store.py
- normalize_email() helper (lowercase + trim)
- Conversations now keyed by sender email address, not thread ID
- Versioned registration storage: data/registrations/<email>/v<N>_<ts>.json
- current.json always reflects the latest version
- save_registration() returns (email_key, version) tuple
- save_registration_version() for updates with change_summary
- get_registration_history() returns all versions in order
models/conversation.py
- Added last_inbound_message_id field for reply threading (not matching)
channels/email_channel.py
- fetch_unread_messages() no longer exposes thread_id
- Conversation matching removed from channel layer (now in agent)
- Removed _resolve_thread_id() — threading headers kept for SMTP only
agent/core.py
- process_message() takes parent_email + inbound_message_id (no thread ID)
- Looks up conversation by normalized email address
- Post-completion handler: detects intent (question / update / new_child)
- Registration updates: diffs old vs new, versions storage, notifies admin
agent/prompts.py
- build_system_prompt() dispatches to registration or post-completion prompt
- Post-completion prompt guides LLM to return intent field
- Reminder language updated: no expiration threats
notifications/notifier.py
- notify_admin() accepts version parameter
- notify_registration_update() sends "Registration Updated" emails with diff
- _build_update_body() includes field-level old→new change summary
main.py
- Poll loop passes parent_email + inbound_message_id to agent (no thread_id)
