//! Cost ledger module for the CFA agent runtime.
//!
//! Per ADR-017 (Audit / Cost / Observability / Security) and the Phase 26
//! PRD, this module implements the native `rusqlite`-backed per-surface
//! cost ledger that backs `cfa cost summary`, `cfa cost budget set`, and
//! `cfa cost budget get`.
//!
//! Tier classification is consumed verbatim from the existing
//! `managed_agent::types::CookbookTier` and `mcp_servers::types::McpServerTier`
//! enums (per RUF-COST-002, RUF-COST-INV-002); this module does not
//! introduce a parallel tiering system.
//!
//! All money is integer `i64` cents to keep the ledger exact.
