feat: voice UI overhaul, schedule integration, self-improving loop closure, editorial redesign

AGENT & PROMPT
- Added show_confirmation client tool to config/agent_config.json (type: client, triggers browser-side confirmation card)
- Upgraded check_availability and record_outcome to full api_schema format with request_body_schema so LLM knows exactly which fields to extract
- Updated prompts/v1_system_prompt.json with:
    - Embedded doctor roster (agent answers roster questions without tool calls)
    - Conversation-history guard: "NEVER re-ask information the patient has already given in this call"
    - show_confirmation trigger instruction (fires once all 5 booking details are confirmed)
    - Doctor availability awareness (which days each doctor works, embedded directly)

SCHEDULE
- Added config/schedule.json — static Mon–Fri schedule for 4 doctors (Emily Chen, James Park, Priya Sharma, Marcus Webb) with per-day free/booked slots
- Each doctor entry includes specialty, appointment types, and day-indexed slot arrays

N8N WORKFLOWS (both require re-import + re-publish)
- workflow_call_handler.json: rewrote check_availability code node to filter by doctor_name and/or day_of_week from tool parameters; only returns free slots; added get_schedule_overview route; improved record_outcome to capture all appointment fields (patient_name, doctor_name, appointment_day, appointment_time, insurance, notes)
- workflow_analysis.json: added HTTP Report Local node (POST localhost:8000/api/report after agent update); strengthened prompt reviser to preserve conversation-history guard and doctor list after each revision; analysis now auto-increments prompt version number

WEB SERVER
- New file: web/server.py — Python HTTP server (replaces python -m http.server)
    - GET / → serves web/index.html and static files from web/
    - GET /api/status → returns current loop state (version, score, changelog, history) from web/iteration_status.json
    - POST /api/report → saves call logs to calls/, analysis reports to analysis/, prompt versions to prompts/, updates iteration_status.json

WEB UI — full rewrite of web/index.html
- THEME: replaced dark glassmorphism with warm editorial palette (cream #FDF6ED, peach #E8A07E, terra #8B5A3C, espresso #3A1E0E)
- TYPOGRAPHY: Cormorant Garamond (serif display) + DM Sans (UI) — no longer uses Inter
- LANDING PAGE (new):
    - Full-viewport warm cream-to-peach gradient hero
    - Large serif "Meet Sarah, your medical receptionist" headline with italic peach accent
    - Three animated floating preview cards (next available, prompt version, specialties)
    - Organic radial blob decorations with CSS float animation
    - Wavy SVG divider between hero and features section
    - Three feature cards (Natural Voice, Schedule Lookup, Self-Improving AI)
    - Dark espresso footer
    - Smooth fade-slide page transition → app on CTA click
- APP — CALL TAB:
    - Multi-layer canvas blob visualizer (3–4 concentric organic blobs with dual-oscillator sin-wave distortion)
    - Blob modes: idle (muted peach), listening (warm sand), speaking (deep coral), connection (gentle)
    - Blob corona glow responds to call state with CSS animations
    - Live transcript (ElevenLabs JS SDK via CDN ESM import): onMessage, onUserTranscript, onAgentSpeaking, onUserSpeaking, onError, onDisconnect callbacks
    - Brown serif state label changes: waiting / connecting / listening / speaking / ended
    - Sidebar: practice info pills, appointment confirmation panel, loop mini-status
    - Doctor card highlight when agent mentions a doctor name in transcript
- APP — DOCTORS TAB:
    - 4 cards with initials avatars (warm terra gradients per doctor)
    - Specialty badge pill in peach
    - Mon–Fri day selector tabs (greyed out unavailable days)
    - Free slots (green) / booked slots (line-through sand) pills
    - Hover lift + highlight on border when mentioned in transcript
- APP — AI LOOP TAB:
    - Prompt version, score (animated SVG ring), calls analyzed metrics
    - Pipeline flow diagram showing all 8 steps from call to UI refresh
    - Prompt change history feed (polled from /api/status every 14 s)
    - Each entry shows version badge, score badge (color-coded), call outcome, timestamp, and individual change bullets
    - Toast notification when version bumps between poll cycles
- APP — CONFIRMATION CARD (sidebar):
    - Hidden until show_confirmation client tool fires
    - Animated slide-in (cubic-bezier spring)
    - Shows patient, doctor, specialty, day, time, type, insurance, location
    - "Book Another Appointment" resets transcript + card

- Step 8 example call script updated with show_confirmation expected behavior
- New section: Self-Improving Loop — How It Works (with judge rubric + weights)
- New section: Doctor Schedule Reference table
