feat: Enterprise DSS architecture implementation

Complete implementation of enterprise design system validation:

Phase 1 - @dss/rules npm package:
- CLI with validate and init commands
- 16 rules across 5 categories (colors, spacing, typography, components, a11y)
- dss-ignore support (inline and next-line)
- Break-glass [dss-skip] for emergency merges
- CI workflow templates (Gitea, GitHub, GitLab)

Phase 2 - Metrics dashboard:
- FastAPI metrics API with SQLite storage
- Portfolio-wide metrics aggregation
- Project drill-down with file:line:column violations
- Trend charts and history tracking

Phase 3 - Local analysis cache:
- LocalAnalysisCache for offline-capable validation
- Mode detection (LOCAL/REMOTE/CI)
- Stale cache warnings with recommendations

Phase 4 - Project onboarding:
- dss-init command for project setup
- Creates ds.config.json, .dss/ folder structure
- Updates .gitignore and package.json scripts
- Optional CI workflow setup

Architecture decisions:
- No commit-back: CI uploads to dashboard, not git
- Three-tier: Dashboard (read-only) → CI (authoritative) → Local (advisory)
- Pull-based rules via npm for version control
