Add quick-start guide for new users

[harryf]

A progressive getting-started guide that puts installation first and gradually builds up to the Algorithm, skills, voice, memory, and security. Written for people who already know Claude Code and want to try PAI without reading the full README first.

From experiences trying to introduce PAI to colleagues, the current README.md is create but very overwhelming and fails the "why does this deserve my attention" test. That may be a feature not a bug but still ... figured a short intro to help people get started without overwhelming them would be useful.

Let's add a comment here that we could have a shell environment for headless available, or CLI. That's too deeply nested in PAI-Install/install.sh

Hey @harryf, thanks for raising this, and sorry it sat for a while.

We're changing how LifeOS ships. Instead of cloning a full ~/.claude directory and running it as a complete system, LifeOS is becoming a skill you install through an agentic installer. The installer hands integration to your own AI, which reads your actual machine (your OS, your paths, your harness) and wires the hooks and system prompt in where they belong.

That's aimed right at what you hit here. The old "one directory, one layout, hope it matches your setup" approach is exactly what broke for so many people, and the new model should handle it far better because your AI does the integration per machine instead of us guessing.

So we're closing this in prep for that release. If it still bites you once the skill-based version is out, reopen or file a fresh one and we'll jump on it. Appreciate you taking the time.
