//! Plan 86 — `PARSER_KIND_*` constants per parser module + the
//! `flowscope::parser_kinds` umbrella re-export. Verify that
//! each parser's `parser_kind()` returns the module constant
//! and that the umbrella re-exports match.
//!
//! Issue #21 (0.18): the `flowscope::parser_kinds` umbrella is
//! deprecated in favour of the typed [`flowscope::ParserKind`]
//! enum. The tests below test backward-compat of the deprecated
//! umbrella one last time before its 0.19 removal — we
//! `#![allow(deprecated)]` the file scope so the deprecation
//! lint doesn't fail CI.
