* feat(devcontainer): add Codespaces config with Claude Code and Vale
Adds GitHub Codespaces / devcontainer configuration:
- Node.js 20 base image with Hugo extended
- Auto-installs: yarn dependencies, Vale CLI, Claude Code CLI
- VS Code extensions: Markdown, Prettier, YAML, Vale
- Port forwarding for Hugo dev server (1313)
- Secrets prompt for ANTHROPIC_API_KEY
Usage:
1. Open repo in Codespaces
2. Add ANTHROPIC_API_KEY to Codespaces secrets
3. Run `claude` to start Claude Code with full network access

- Remove specific Hugo version (use feature default)
- Add codespaces.openFiles for better UX
