New skill files:
- clean-code.instructions.md — naming, functions, classes, error handling,
formatting, DRY/KISS/SOLID, Helm YAML conventions
- clean-architecture.instructions.md — dependency rule, layers, boundaries,
SOLID foundation, Helm as outermost layer
- helm.instructions.md — resource ownership, values hygiene, required vs
defaults, umbrella chart pattern, two-file values layering, KISS principle,
hook ordering, config files pattern, dependency caching, template testing
Register all three in ai-root-instructions.md skills list and routing table.
Remove .ai from .gitignore — .ai/ is the product in this repo and must be
tracked; the apply.sh skip-by-marker mechanism prevents changes to other repos.
