feat: AI SMS reminder flow with two-message intro, smart reschedule with availability checks
- Reminder flow: send AI self-introduction as message 1 (Twilio REST API), intent response as message 2 (TwiML) so intro always arrives first - LangGraph reminder graph: classify yes/no/other from patient reply; 'no' now asks 'When would you like to reschedule?' directly - Reschedule flow: new asked_reschedule_datetime stage replaces multi-step ASAP/next-week flow - Date-only reply (e.g. '5/18'): ask for time separately, then confirm - Date+time reply (e.g. '5/18 at 10am'): go straight to confirmation - new asked_reschedule_time_for_date and asked_reschedule_confirm_datetime stages - Date/time parsing: regex handles M/D and am/pm formats first; falls back to Gemini for natural language - Day-level office hours check: if requested day is closed (e.g. Sunday), reply 'Our office is closed on [date]. Choose another day?' - Time-level office hours check: if requested time is outside working hours (e.g. 12pm during lunch), reply with actual hours (e.g. '9:00 am – 12:00 pm and 1:00 pm – 5:00 pm') - Slot availability check: verifies no conflicting appointment for same staff member - After appointment confirmed: patient thank-you reply triggers warm closing with upcoming appointment time - Schedule page: office hours summary bar above grid showing today's configured hours with link to settings Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
