anodizer 0.7.0

//! Integration coverage for `builder: prebuilt` — the import-pre-built-binary
//! builder that skips `cargo build` and stages an already-produced binary
//! into the release pipeline.
//!
//! Each test stages a fake binary outside `dist/` (per the warning
//! that the release pipeline removes `dist/` between runs), points the
//! config's `prebuilt.path` template at it, and asserts the artifact lands
//! with the expected metadata. Negative tests cover the four config-load
//! validations (missing path, missing targets, mutual-exclusion with
//! `cross_tool`, `cross:` crate-level strategy).
