fix(neovim): disable helm_ls internal yamlls diagnostics for Jinja2 templates

- helm_ls spawns yamlls as internal subprocess for YAML validation
- This causes "Yamlls:" prefixed errors on Jinja2 cookiecutter templates
- Set diagnosticsLimit = 0 to disable yamlls diagnostics entirely
- Preserves hover and completion features from yamlls
- Solves triple-layer templating issues (Jinja2 + Helm + YAML)
