feat: add GETTING-STARTED.md - from demo to daily driver

Practical 6-step guide that takes users from "clone and explore"
to "personal AI assistant I text from my phone":

1. Personalize CLAUDE.md (30 min)
2. Set up phone channel - iMessage/Telegram/Discord (10 min)
3. Keep session alive with tmux (5 min)
4. Write first personal skills with 3 real examples (15 min)
5. Connect external tools via MCP (15 min per tool)
6. Let it learn over time (ongoing)

Includes: "what your day looks like after setup" scenarios,
honest expectations, and quick reference table.

README updated with two-path entry: demo mode vs daily driver.

-## Quickstart
+## Two paths
+
+**"Show me what it can do"** - Browse `examples/`, read `feature-map.md`,
+try the demo prompts. You will understand what Claude Code is capable of.
+
+**"Help me actually use it"** - Read **[GETTING-STARTED.md](GETTING-STARTED.md)**.
+Six concrete steps that take you from demo to personal daily driver:
+personalize CLAUDE.md, set up phone access, write your own skills,
+and build the setup into how you actually work. About one hour total.
