Root cause of the Qt 6.11.0/6.11.1 and KDE 6.10.0/6.28.0 divergences: a version
bump rewrote recipe tar=/blake3= but never propagated into the vendored source/
tree (the actual build input), and nothing caught the resulting drift.
Adds the missing pieces (see local/docs/VERSIONING.md):
- sync-recipe-source.sh: propagation engine — rebases a vendored source/ onto
the recipe's declared version (pristine + patches + captured baked delta),
with baked-shim preservation and corruption drop; reports patches/shims that
need a manual rebase instead of applying with fuzz.
- verify-external-source-versions.sh: preflight gate (build-preflight.sh Phase
1.0C, REDBEAR_SKIP_EXTERNAL_SOURCE_CHECK) that fails loudly on recipe-vs-
source-vs-tarball version divergence — the tar-recipe analogue of
verify-fork-functions.sh.
- bump-graphics-recipes.sh: now calls the sync engine after a bump, so a bump
can never again silently no-op on a vendored recipe.
- source/.redbear-src-version stamp; seeded for the corrected qt modules.
