refactor: complete migration to template-v2 architecture
- Remove legacy template.svg files from example/ and my-project/ - Simplify generator.js by removing generateHardcoded method (326→210 lines, -36%) - Add strict template validation with clear error messages - Remove all fallback mechanisms - template-v2.svg format now required - Clean up tests: remove hardcoded generation tests, keep template-based tests - Add comprehensive e2e tests (large datasets, edge cases, error handling) - Update documentation: mark REFACTORING_PLAN.md complete, add TEMPLATE_V2_GUIDE.md - All 56 tests passing (16 engine + 25 generator + 15 integration) BREAKING CHANGE: Old template.svg format no longer supported. Must use template-v2.svg with <g id="*-template"> elements in defs section. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
