feat: integrate Memento MCP for shared memory across agents

- Add MEMENTO_MCP_SSE_URL/ACCESS_KEY/REMOTE_PATH to readEnvFile
- Merge .env vars into cleanEnv for runner process inheritance
- Claude Code runner: add memento-mcp via mcp-remote in mcpServers
- Codex runner: inject memento-mcp section into config.toml
- Various improvements: CI watch, task scheduler, DB, IPC auth
