Greptile Summary

This PR prepares the v0.3.0 release by bumping all Helm chart and image references from their pre-release state to the v0.3.0 tag across the three charts (topograph, node-data-broker, node-observer).

• Updated appVersion in all three Chart.yaml files from the scaffolded placeholder "1.16.0" to "v0.3.0"
• Pinned all ghcr.io/nvidia/topograph image tags from the mutable main branch tag to the fixed v0.3.0 release tag (root chart values.yaml, node-observer/values.yaml, and the initc init-container in node-data-broker/values.yaml)
• All chart version fields and inter-chart dependency version references remain consistently at 0.3.0 (unchanged from the prior state)
• No template logic, RBAC, or configuration changes are included — this is a pure version-bump release PR

Confidence Score: 5/5

• This PR is safe to merge — it is a mechanical, internally consistent version bump with no logic changes.
• All six changed files perform the same two mechanical operations: replacing the Helm scaffold placeholder appVersion "1.16.0" with "v0.3.0", and pinning mutable "main" image tags to the fixed "v0.3.0" release tag. The changes are fully consistent across all three charts and their sub-charts, no template logic is touched, and there are no structural issues.
• No files require special attention.
