feat(config): add .claude/rules/ for modular auto-loaded instructions

Introduces 5 rules files following Anthropic's recommended pattern
for splitting large CLAUDE.md files. Rules auto-load every session
and separate CLI reference material from core project identity.

- tea-cli.md: Gitea CLI reference, PR creation, protected branches
- git-safety.md: staging rules, commit conventions (from git-commit skill)
- project-structure.md: full annotated directory tree
- team-patterns.md: model selection, large content push pattern
- local-services.md: Gitea/Qdrant/Ollama endpoints
