Two corrections after finding the Qt offline-source model:
1. The Qt recipes intentionally COMMIT source.tar as the offline source
(qtbase/qtsvg/qtshadertools all do). My previous commit wrongly added a
local/recipes/**/source.tar ignore rule; revert it -- source.tar is durable
here, only source/ is the fork model.
2. Real deficiency: the pre-cook offline decision honored only the
REDBEAR_ALLOW_UPSTREAM env var, while the main `make live` phase also goes
online for the --upstream flag (ALLOW_UPSTREAM=1). So `--upstream` alone left
the pre-cook OFFLINE but the main phase ONLINE -- a package missing its
source.tar cache (e.g. right after the stale 6.11.0 tars were purged) failed
the pre-cook with "Opening file for blake3 failed ... source.tar: No such
file". Make the pre-cook honor ALLOW_UPSTREAM too, matching the main phase.
