//! HTTP API routes for the node capability registry.
//!
//! - POST   /api/mesh/capabilities/:peer_name  — register capabilities
//! - GET    /api/mesh/capabilities              — list all capabilities
//! - GET    /api/mesh/capabilities/:peer_name   — get peer capabilities
//! - DELETE /api/mesh/capabilities/:peer_name   — remove peer capabilities
//! - POST   /api/mesh/capabilities/query        — find capable peers
