📝 Walkthrough

Walkthrough

This PR introduces new API endpoints and handler functions to retrieve and copy chat messages between conversations. It includes validation utilities for request parameters and body payloads, updates memory persistence operations to support bulk inserts and deletions, and modifies existing chat completion functions to align with the new bulk-insert pattern.

Changes

Cohort / File(s)	Summary
API Routes app/api/chats/[id]/messages/route.ts, app/api/chats/[id]/messages/copy/route.ts	New Next.js route handlers exposing GET and POST endpoints with CORS preflight support; delegates to corresponding handler functions.
Message Handlers lib/chats/getChatMessagesHandler.ts, lib/chats/copyChatMessagesHandler.ts	Implements async request handling with validation, memory retrieval/manipulation, and structured JSON responses with error management.
Request Validation lib/chats/validateGetChatMessagesQuery.ts, lib/chats/validateCopyChatMessagesBody.ts	Zod-based validation schemas for query parameters and request body; enforces constraints (UUID format, source ≠ target chat IDs) and returns early-exit NextResponse on failure.
Supabase Memory Operations lib/supabase/memories/insertMemories.ts, lib/supabase/memories/deleteMemories.ts	Refactors insertMemories to accept arrays instead of single objects and return counts; adds new deleteMemories utility for bulk deletion by room ID.
Chat Persistence Updates lib/chat/saveChatCompletion.ts, lib/chat/setupConversation.ts	Adapts existing functions to call insertMemories with array syntax and adds explicit updated_at timestamp construction in response objects.
