chore(release): 2.2.4 [skip ci]

- Remove Helm CLI from Dockerfile (OOMKilled sidecar was the only consumer)
- Disable helm MCP sidecar in chart values (uses 194Mi+ idle, OOMKills at 256Mi)
- Remove helm from .mcp.json
- Disable Docker layer cache in build-and-push workflow (cache serves stale
  layers missing tool binaries - DO NOT RE-ENABLE)
