chore(vitepress): exclude AI agent docs from site build

- Add srcExclude pattern in docs/.vitepress/config.mts
  - Exclude **/AGENTS.md from VitePress build
  - Exclude **/CLAUDE.md from VitePress build
  - Prevents AI agent knowledge base from appearing on public website

- Update .gitignore
  - Add .claude/ directory exclusion
  - Ensure AI agent configuration files remain private

Impact: AGENTS.md and CLAUDE.md files remain in repository for AI agent
use but are no longer built into HTML and exposed on the website.

Build verification: npm run build passed, no AGENTS.html in dist/
