refactor(skills): streamline skill hierarchy with /install as primary entry point

[pmTouchedTheCode]

Summary

• Hide advanced/specialized skills from slash command menu to reduce clutter for new users
• Consolidate onboarding experience around /install as the primary SDK setup entry point
• Enhance /doctor for comprehensive health checks and /ios-setup as a sub-skill

Changes

• skills.ts: Add HIDDEN_PACKAGE_SKILLS and HIDDEN_LOCAL_SKILLS sets to control menu visibility
• install/SKILL.md: Major rewrite as comprehensive orchestrator with visual progress tracking and iOS NSE support
• doctor/SKILL.md: Expanded health check capabilities
• ios-setup/SKILL.md: Refactored as sub-skill invoked by /install
• Documentation: Updated README.md and llms.txt to reflect new skill hierarchy
• Tests: Updated slash-command-menu tests for hidden skills

Test plan

• Run bun test to verify all tests pass
• Run bun run dev and verify hidden skills don't appear in / autocomplete
• Verify hidden skills still work when typed directly (e.g., /integration)
• Test /install flow on a sample iOS project
• Test /doctor health check output

Closing this draft PR — the changes are no longer applicable after the command-mode architecture refactor in #22.

What happened:

• Package skills (@clix-so/clix-agent-skills) were removed entirely, making HIDDEN_PACKAGE_SKILLS unnecessary
• LOCAL_SKILLS reduced to install/doctor only (debug removed)
• install/SKILL.md and doctor/SKILL.md rewritten with PreparationContext-based architecture
• ios-setup moved from skills to UI components
• README/llms.txt updated differently by subsequent commits

The goals of this PR (simplify skill hierarchy, /install as primary entry) are now achieved through the preparation-based task flow in #22.
