feat: agentic setup integration snippets on tool detail pages

[nimit2801]

Summary

Each tool detail page shows how to integrate that specific tool into Claude Code, Codex, Cursor, and Windsurf. Makes the catalog actionable — developers go from discovery to integration in one page.

Scope

• New ToolIntegrations component on ToolDetail
• Tab switcher: Claude Code / Codex / Cursor / Windsurf
• Each tab shows a copy-ready snippet: CLAUDE.md entry, .cursorrules reference, system prompt, or package install
• Snippets dynamically built from tool.install_command + tool.name + tool.use_cases[0]
• Only show if tool has install_command or github_url

Effort: 3 points
