- Detect claude CLI availability; if present, use `claude mcp add`
with --transport http (Streamable HTTP) instead of writing .mcp.json
- Fall back to .mcp.json for environments without claude CLI
- Install skills directly to ~/.claude/skills/ (where Claude Code reads them)
- Remove marketplace/plugin registration (not used by Claude Code)
