Updates helm chart commitizen config to recognize MCP server version
bump commits (which update appVersion in Chart.yaml) as valid triggers
for helm chart version bumps.
Problem:
- When MCP server version bumps, it updates Chart.yaml appVersion
- Helm chart commitizen only matched "(helm)" scoped commits
- Result: appVersion updated but chart version not bumped
Solution:
- Extended changelog_pattern to include "bump: version X → Y" commits
- Now helm chart version will bump when either:
1. Commits with (helm) scope are made, OR
2. MCP server version bumps (updating appVersion)
This ensures chart version stays in sync with appVersion updates.
