c3cd353f2f feat: implement subscription system with conversation limits
Implement complete backend subscription system that limits free users to 10
AI conversations per month and offers Premium tier ($10/month or $100/year)
with unlimited conversations.

Changes:
- Add User subscription fields (tier, status, limits, counters)
- Create Subscription model to track Stripe subscriptions
- Implement conversation limit enforcement in chat API
- Add subscription checkout and customer portal APIs
- Update Stripe webhook to handle subscription events
- Add subscription utility functions (limit checks, tier management)
- Add comprehensive subscription translations (en, ro, es, it)
- Update environment variables for Stripe price IDs
- Update footer "Sponsor Us" link to point to /donate
- Add "Sponsor Us" button to home page hero section

Database:
- User model: subscriptionTier, subscriptionStatus, conversationLimit,
  conversationCount, limitResetDate, stripeCustomerId, stripeSubscriptionId
- Subscription model: tracks Stripe subscription details, periods, status
- SubscriptionStatus enum: ACTIVE, CANCELLED, PAST_DUE, TRIALING, etc.

API Routes:
- POST /api/subscriptions/checkout - Create Stripe checkout session
- POST /api/subscriptions/portal - Get customer portal link
- Webhook handlers for: customer.subscription.created/updated/deleted,
  invoice.payment_succeeded/failed

Features:
- Free tier: 10 conversations/month with automatic monthly reset
- Premium tier: Unlimited conversations
- Automatic limit enforcement before conversation creation
- Returns LIMIT_REACHED error with upgrade URL when limit hit
- Stripe Customer Portal integration for subscription management
- Automatic tier upgrade/downgrade via webhooks

Documentation:
- SUBSCRIPTION_IMPLEMENTATION_PLAN.md - Complete implementation plan
- SUBSCRIPTION_IMPLEMENTATION_STATUS.md - Current status and next steps

Frontend UI still needed: subscription page, upgrade modal, usage display

a01377b21a feat: implement AI chat with vector search and random loading messages
Major Features:
-  AI chat with Azure OpenAI GPT-4o integration
-  Vector search across Bible versions (ASV English, RVA 1909 Spanish)
-  Multi-language support with automatic English fallback
-  Bible version citations in responses [ASV] [RVA 1909]
-  Random Bible-themed loading messages (5 variants)
-  Safe build script with memory guardrails
-  8GB swap memory for build safety
-  Stripe donation integration (multiple payment methods)

AI Chat Improvements:
- Implement vector search with 1536-dim embeddings (Azure text-embedding-ada-002)
- Search all Bible versions in user's language, fallback to English
- Cite Bible versions properly in AI responses
- Add 5 random loading messages: "Searching the Scriptures...", etc.
- Fix Ollama conflict (disabled to use Azure OpenAI exclusively)
- Optimize hybrid search queries for actual table schema

Build & Infrastructure:
- Create safe-build.sh script with memory monitoring (prevents server crashes)
- Add 8GB swap memory for emergency relief
- Document build process in BUILD_GUIDE.md
- Set Node.js memory limits (4GB max during builds)

Database:
- Clean up 115 old vector tables with wrong dimensions
- Keep only 2 tables with correct 1536-dim embeddings
- Add Stripe schema for donations and subscriptions

Documentation:
- AI_CHAT_FINAL_STATUS.md - Complete implementation status
- AI_CHAT_IMPLEMENTATION_COMPLETE.md - Technical details
- BUILD_GUIDE.md - Safe building guide with guardrails
- CHAT_LOADING_MESSAGES.md - Loading messages implementation
- STRIPE_IMPLEMENTATION_COMPLETE.md - Stripe integration docs

2d27eae756 Enhance RAG system to support multiple vector databases and improve AI chat functionality
- Update vector-search.ts to query all available vector tables per language instead of single table
- Add getAllVectorTables() function to discover all language-specific vector tables
- Enhance searchBibleHybrid() to query multiple tables and merge results by relevance score
- Enhance searchBibleSemantic() to combine results from all available vector databases
- Add comprehensive error handling and logging for vector search operations
- Improve Azure OpenAI content filtering detection and error handling
- Add test-vector API endpoint for database diagnostics and debugging
- Fix environment configuration with complete Azure OpenAI settings
- Enable multi-translation biblical context from diverse Bible versions simultaneously

Tested: Romanian chat works excellently with rich biblical context and verse citations
Issue: English requires vector table creation - 47 English Bible versions exist but no vector tables

24c0577f44 Fix chat history authentication and conversation saving
- Fix critical async/await bug in chat API token verification
- Add comprehensive authentication debugging logs
- Fix conversations API Zod schema validation for query parameters
- Remove problematic CircularProgress import causing build warnings
- Improve error handling and user feedback in chat component

The main issue was that verifyToken() was called without await, causing
the chat API to receive a Promise object instead of the user payload,
resulting in undefined userId and failed conversation persistence.
