chore(firehose): bump image to 0.8.1 and add podAnnotations support

[rsbh]

Bumps the firehose image tag to 0.8.1 and adds podAnnotations support.

Image bump

• values.yaml: firehose.image.tag 0.8.0 → 0.8.1
• Chart.yaml: chart version 0.1.4 → 0.1.5, appVersion 0.7.1 → 0.8.1 (was stale)
• README.md: corrected the firehose.image.tag default row (was documented as 1.1.0)

podAnnotations

• templates/deployment.yaml: render .Values.podAnnotations on pod template (alongside checksum/config), same pattern as app chart
• values.yaml: add podAnnotations: {}
• README.md: document podAnnotations

📝 Walkthrough

Walkthrough

The Firehose Helm chart version changes from 0.1.4 to 0.1.5. Its app version and configured default image tag change to 0.8.1. The README documents the updated default image tag. The chart adds a podAnnotations value, which the Deployment template renders under pod template annotations when set.

Protect the generated checksum/config annotation.

podAnnotations has no reserved-key validation. If it contains checksum/config, the template emits duplicate YAML keys. The parser may reject the manifest or override one value. Merge the maps so the generated checksum takes precedence.

🐛 Suggested fix

       annotations:
-        checksum/config: {{ include (print $.Template.BasePath "/configmap-firehose.yaml") . | sha256sum }}
-        {{- with .Values.podAnnotations }}
-        {{- toYaml . | nindent 8 }}
-        {{- end }}
+        {{- $checksum := include (print $.Template.BasePath "/configmap-firehose.yaml") . | sha256sum }}
+        {{- $annotations := merge (dict "checksum/config" $checksum) .Values.podAnnotations }}
+        {{- toYaml $annotations | nindent 8 }}
