Add Cursor as a fifth supported runtime alongside Claude Code, OpenCode,
Gemini, and Codex. Cursor uses skills (~/.cursor/skills/gsd-*/SKILL.md)
like Codex, with tool name mappings (Bash→Shell, Edit→StrReplace),
subagent type conversion, and full Claude-to-Cursor content adaptation
including project conventions (CLAUDE.md→.cursor/rules/, .claude/skills/
→.cursor/skills/) and brand references.
Includes install, uninstall, interactive prompt, help text, manifest
tracking, and .cjs/.js utility script conversion.
Made-with: Cursor
