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.

+# Rippr — source snapshot
+
+Point-in-time export of the Rippr working tree, exported with `git archive HEAD`
+(tracked files only — no build outputs, no `local.properties`, no nested `.git`).
+
+**Commit:** `2f76983` — "Fix live readout and blank map, both found on the first real ride"
+
+## Two copies live here, for different jobs
+
+| File | Purpose |
+|---|---|
+| `rippr-src/` | Browsable source. No history — a snapshot that will drift. |
+| `rippr-full-history.bundle` | Full git history (18 commits). The real backup. |
+
+The canonical repo is `~/dojo/rippr`, which **has no git remote** — it exists only on that
+machine. The bundle is therefore the only off-machine copy of the history.
+
+## Restoring from the bundle
+
+```bash
+git clone rippr-full-history.bundle rippr
+cd rippr
+echo "sdk.dir=$HOME/Library/Android/sdk" > local.properties
+./gradlew assembleDebug
+```
+
+Verified: the bundle reports "records a complete history" and clones cleanly to all 18
+commits.
+
+## Building
+
+Needs JDK 17–21 (AGP does not support 25) and the Android SDK with platform 35 and
+build-tools 35. See `docs/v2/01-baseline.md`.
+
+```bash
+./gradlew assembleDebug testDebugUnitTest lintDebug   # 84 unit tests
+./gradlew connectedDebugAndroidTest                   # 46, needs a device
+```
