- Add crates/tui/assets/skills/skill-creator/SKILL.md (ported from
OpenAI codex repo, MIT-licensed; all Codex→deepseek / ~/.codex→~/.deepseek
replacements applied; MIT attribution comment at top).
- Convert crates/tui/src/skills.rs → skills/mod.rs + new skills/system.rs.
install_system_skills() writes the bundled SKILL.md on fresh install or
version bump; respects user-deleted directories; idempotent by design.
Version marker at ~/.deepseek/skills/.system-installed-version.
- Wire install_system_skills() into run_interactive() (main.rs) before the
TUI mounts; errors are non-fatal (logged as warnings).
- Add /skill new as an alias for /skill skill-creator in commands/skills.rs.
- 7 unit tests covering fresh install, idempotence, user-deleted dir, version
bump, uninstall (all pass).
