node-app-build 5.20.3

//! `node-app validate`
//!
//! Runs the full set of v2-aware validations on a project's `manifest.json`:
//!   - JSON Schema (manifest-v2.json) when available
//!   - Path safety on entrypoint / ui_path
//!   - Capability requirement parsing
//!   - ABI compatibility
//!   - Tier policy: native cdylib at the apt path is rejected
//!
//! Returns the parsed `AppManifest` so callers (e.g. `package`) can reuse it.
