fix(ci): quote color values in labels.yml

Fixed YAML parsing error where hex color values were interpreted as
numbers instead of strings for plugin labels.

Changes:
- .github/labels.yml: Added quotes around color values for plugin:* labels
- CLAUDE.md: Added best practices for comprehensive issue reports
