feat: add AI chat widget powered by ADK Go 1.0
Visitors can ask questions about the CV via a floating chat panel. The agent uses Gemini to answer questions about experience, projects, skills, and education by querying the cached CV JSON data. - internal/chat/agent.go: LLM agent with query_cv tool that searches CV data by section (experience, projects, skills, etc.) with keyword filtering - internal/chat/handler.go: POST /api/chat endpoint with session management, graceful degradation when GOOGLE_API_KEY is not set - chat-widget.html: HTMX-powered floating chat panel with Hyperscript toggle - _chat.css: Responsive chat UI with dark theme support - Wired into existing architecture via dependency injection (CVHandler, routes, main.go) — zero breaking changes, all existing tests pass
