rvt 0.4.0

//! Q5.2 — FieldType classification coverage on real project files.
//!
//! For each `.rvt` under the corpus dir, parses `Formats/Latest` and
//! counts how many of the schema's declared fields the 11-discriminator
//! `FieldType` enum classified cleanly vs fell through to `Unknown`.
//!
//! Validates the "100% classified" claim across project files (was
//! originally measured on family files only). Path resolves via
//! `RVT_PROJECT_CORPUS_DIR` (default
//! `/private/tmp/rvt-corpus-probe/magnetar/Revit`).
