compat.boost-config.lua

-- Form B inline descriptor for Boost.Config 1.92.0 — the root of this index's
-- modular-boost header family. Each boostorg/<lib> repository is packaged from
-- its OWN release-train tag (`boost-1.92.0`) instead of the ~224 MiB monolith,
-- mirroring how vcpkg splits Boost into per-library ports: consumers download
-- exactly the closure they use (Config alone is ~300 KiB of archives).
--
-- Family wiring (verified by grepping every `<boost/...>` include across each
-- package's include tree AND cross-checked against each repo's CMakeLists
-- INTERFACE link line):
--     config           -> (nothing)
--     assert           -> config
--     type-traits      -> config
--     throw-exception  -> assert, config
--     uuid             -> all four above
-- The five shipped header sets are pairwise disjoint, so five `*/include`
-- include roots union into one coherent `boost/` tree with no collisions.
-- Upgrades move the WHOLE train together (every boostorg repo tags the same
-- release); partial trains are untested territory.
--
-- Header-only, traditional `#include` consumption only — no module unit here.
-- Upstream ships none for Config, and this family deliberately stays on the
-- textual path (see compat.jwt-cpp / tests/examples/boost-*).
--
-- No CN mirror yet: plain-string upstream URL, like boost-ext.ut. Consumers in
-- CN fall back to the GLOBAL source until a maintainer backfills gitcode.
