fix(helm): include MCP server version bumps in changelog pattern

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.
