51/// Oxios kernel System Call API — composed of 13 domain Facades.
52///
53/// Each Facade groups related system calls:
54/// - [`StateApi`]     — data persistence, sessions
55/// - [`AgentApi`]     — agent lifecycle, budgets, memory
56/// - [`SecurityApi`]  — auth, audit trail, RBAC, approvals
57/// - [`PersonaApi`]   — multi-persona management
58/// - [`ExtensionApi`] — programs, skills, host tools
59/// - [`McpApi`]       — MCP server bridge
60/// - [`MountApi`]      — Mount (path alias) management (RFC-025)
61/// - [`ProjectApi`]    — Project management, memory linking
62/// - [`ExecApi`]      — execution config, access management
63/// - [`A2aApi`]       — agent-to-agent communication
64/// - [`EngineApi`]    — LLM engine providers, models, config
65/// - [`KnowledgeBase`] — markdown note management (kernel-free, via oxios-markdown)
