Add Rippr source snapshot and full-history bundle

Two copies for two jobs. rippr-src/ is a browsable git archive export of
the tracked tree at 2f76983 - no build outputs, no local.properties, no
nested .git - which is convenient to read in gitea but carries no history
and will drift.

rippr-full-history.bundle is the real backup: all 18 commits, verified as
"records a complete history" and test-cloned before committing. This
matters because ~/dojo/rippr has no git remote and otherwise exists only
on one machine.

rippr-src/SNAPSHOT.md explains the difference and how to restore.
