v2.2.9

Helm chart fix: liveness probe timeout

No app code changes — chart-only release.

• Liveness probe timeoutSeconds: 10 → 30
• Liveness probe failureThreshold: 3 → 5
• Chart version bumped to 2.0.8
• appVersion corrected to 2.2.8 (was stale at 2.1.5)

Background: The app loads ML embeddings for ~5,800 plants and can experience GC pauses during bot scanner traffic, causing the 10s probe to time out and trigger unnecessary pod restarts. This gives the app adequate grace before being declared unhealthy.

To adopt this chart version, update .holo/sources/choose-native-plants.toml in your cluster repo:
