The ::text cast on search_providers.id prevented sqlc from inferring
nullability via LEFT JOIN, generating a non-nullable string field that
crashes when the bot has no search provider bound.
Catch unique constraint violation (SQLSTATE 23505) during route creation
in ResolveConversation and fall back to Find, preventing duplicate key
errors when concurrent inbound messages hit the same chat simultaneously.
Add shared IsUniqueViolation helper to internal/db.
Propagate conversation type (direct/group/thread) from channel adapters
all the way to the agent prompt. Store conversation_type on bot_channel_routes
so the bot knows whether a message originates from a p2p chat, group, or thread.
Schema changes are folded into the 0001 init migration (destructive update).
- Accept standard mcpServers item format (command/args/env/url/headers)
- Auto-infer connection type: command -> stdio, url -> http/sse
- Add PUT /bots/:bot_id/mcp/import for batch import from mcpServers dict
- Add GET /bots/:bot_id/mcp/export for standard format export
- Add UpsertMCPConnectionByName SQL for import upsert by name
- Preserve is_active state on import upsert
- Rename chat module to conversation with flow-based architecture
- Move channelidentities into channel/identities subpackage
- Add channel/route for routing logic
- Add message service with event hub

- Update database schema for conversations, messages and channel routes
- Add @memoh/shared package for cross-package type definitions
Align channel identity and bind flow across backend and app-facing layers, including generated swagger artifacts and package lock updates while excluding docs content changes.
- Refactor channel manager with support for Sender/Receiver interfaces and hot-swappable adapters.
- Implement identity routing and pre-authentication logic for inbound messages.
- Update database schema to support bot pre-auth keys and extended channel session metadata.
- Add Telegram and Feishu channel configuration and adapter enhancements.

Major changes:
1. Core Architecture: Decoupled Bots from Users. Bots now have independent lifecycles, member management (bot_members), and dedicated configurations.
2. Channel Gateway:
- Implemented a unified Channel Manager supporting Feishu, Telegram, and Local (Web/CLI) adapters.
- Added message processing pipeline to normalize interactions across different platforms.
- Introduced a Contact system for identity binding and guest access policies.
3. Database & Tooling:
- Consolidated all migrations into 0001_init with updated schema for bots, channels, and contacts.
- Optimized sqlc.yaml to automatically track the migrations directory.
4. Agent Enhancements:
- Introduced ToolContext to provide Agents with platform-aware execution capabilities (e.g., messaging, contact lookups).
- Added tool logging and fallback mechanisms for toolChoice execution.
5. UI & Docs: Updated frontend stores, UI components, and Swagger documentation to align with the new Bot-centric model.
- Update LLMClient test to match NewLLMClient signature by passing nil logger
- Add nil check for logger in NewLLMClient to prevent panic, defaulting to slog.Default()
