feat: modular setup wizard with section subcommands and tool-first UX

Restructure the monolithic hermes setup wizard into independently-runnable
sections with a category-first tool configuration experience.

Changes:
- Break setup into 5 sections: model, terminal, gateway, tools, agent
- Each section is a standalone function, runnable individually via
  'hermes setup model', 'hermes setup terminal', etc.
- Returning users get a menu: Quick Setup / Full Setup / individual sections
- First-time users get a guided walkthrough of all sections

Tool Configuration UX overhaul:
- Replace flat API key checklist with category-first approach
- Show tool types (TTS, Web Search, Image Gen, etc.) as top-level items
- Within each category, let users pick a provider:
  - TTS: Microsoft Edge (Free), OpenAI, ElevenLabs
  - Web: Firecrawl Cloud, Firecrawl Self-Hosted
  - Image Gen: FAL.ai
  - Browser: Browserbase
  - Smart Home: Home Assistant
  - RL Training: Tinker/Atropos
  - GitHub: Personal Access Token
- Shows configured status on each tool and provider
- Only prompts for API keys after provider selection

Also:
- Add section argument to setup argparse parser in main.py
- Update summary to show new section commands
- Add self-hosted Firecrawl and Home Assistant to tool setup
- All 2013 tests pass
