Asta CLI Installer

Installs the asta CLI for agents that don't install it automatically via a plugin hook.

When to invoke

• asta is not on PATH (e.g., command -v asta returns nothing, or running asta ... reports "command not found")
• A subcommand, option, or output field that should exist according to another skill is missing — that signals an outdated install
