anodizer 0.7.0

//! Integration tests for `anodizer init --version-files`.
//!
//! The enrollment flow discovers TRACKED, text files that embed the current
//! version (bare or `v`-prefixed) and writes the user's selection into the
//! top-level `version_files:` block of an existing `.anodizer.yaml`, preserving
//! the file's comments and key order. Drives the non-interactive `-y` path
//! (the interactive multi-select cannot be driven from a test harness); the
//! discovery/filter/write logic is shared with the prompt.
