Fix corrupted splunk-operator-3.0.0.tgz causing Helm test failures

[gabrielm-splunk]

Problem

After merging PR #1832 to restore helm support for 3.0.0, helm-tests are failing with:

Error: INSTALLATION FAILED: template: splunk-enterprise/charts/splunk-enterprise/templates/enterprise_v4_ingestorcluster.yaml:1:14: 
executing "splunk-enterprise/charts/splunk-enterprise/templates/enterprise_v4_ingestorcluster.yaml" at <.Values.ingestorCluster.enabled>: 
nil pointer evaluating interface {}.enabled

Root Cause

The splunk-operator-3.0.0.tgz file was corrupted - it contained the full splunk-enterprise chart package (4.5MB) instead of just the splunk-operator chart (5.8KB). This caused Helm to load a stale splunk-enterprise as a subchart within the operator chart, leading to nested template path errors.

File size comparison:

• Corrupted: splunk-operator-3.0.0.tgz = 4.5MB (contains full splunk-enterprise chart)
• Correct: splunk-operator-3.0.0.tgz = 5.8KB (contains only operator chart)
• Reference: splunk-operator-3.1.0.tgz = 6.7KB (correct structure)

The corruption happened in multiple "Restore helm chart version 3.0.0 to repository index" commits (b9766dd and related).

Solution

Restored correct tgz file by extracting the good version from git history (commit a3737ba).
The file now contains only splunk-operator chart content, not nested splunk-enterprise.

Testing

• ✅ File structure validated: starts with splunk-operator/ directory (not splunk-enterprise/)
• ✅ File size verified: 5.8KB (correct for operator-only chart)

Future Work

Validation tooling (CI/CD workflow and validation script) has been saved to branch helm-validation-tooling-future for a separate PR.

Files Changed

• helm-chart/splunk-enterprise/charts/splunk-operator-3.0.0.tgz - Restored correct 5.8KB version
