oxipage-core 0.7.0

//! Site profile data model — used by both CLI and console for `sites.toml`.
//!
//! File I/O (`load`/`save` with permissions) lives in `oxipage` (CLI crate)
//! under `crate::sites`. This module provides only the type definitions plus
//! in-memory data access.
//!
//! v2 SSG: each site = local directory with its own `oxipage.toml` + `oxipage.db`.
//! Remote endpoint/token model removed (spec D1, D7).
