Pull request overview

This PR shifts default “prompt/script” assets and skill packaging away from in-package builtin_skills toward system data directories, and adds startup initialization to copy default .aish prompt scripts into the user scripts directory.

Changes:

• Remove built-in skill root discovery from SkillManager (skills now expected to be present under the user skills directory, seeded by packaging/install).
• Add config startup initialization to copy default .aish prompt scripts from system locations into the user scripts directory (best-effort, non-overwriting).
• Update packaging/install to ship prompt scripts and templates via Makefile + PyInstaller datas, and add a new packaged Debian skill (prompt-designer).
