flowscope 0.22.0

//! Plan 86 — `PARSER_KIND_*` constants per parser module. Verify
//! that each parser's `parser_kind().as_str()` returns its module
//! constant and that the slug vocabulary is byte-stable.
//!
//! Issue #139 (0.22): the deprecated `flowscope::parser_kinds`
//! umbrella re-export was removed — the typed
//! [`flowscope::ParserKind`] enum (`.as_str()`) is the single
//! source of the slug vocabulary. These tests pin the module
//! constants against it.
