Fix installation instructions - one-line curl install doesn't work

- Remove broken one-line curl install commands
- Add proper git clone + run installer instructions
- Add clear explanation that repo must be cloned first
- Fix Windows WSL and Git Bash instructions
- Add warning about curl in PowerShell

The installer script needs access to files in the repository
(skills/, agents/, hooks/, etc.) so one-line piping won't work.

-> **⚠️ Important:** Do NOT run curl commands directly in PowerShell. The syntax is different. Use WSL or Git Bash for bash commands.
+> **⚠️ Important:** The installer requires access to files in the repository (skills, agents, hooks, etc.). One-line curl installs won't work - you must clone the full repository first.
