/iblai-vibe-agent-search

Add an Agent Search page -- a searchable, filterable agent browser with four sections: starred agents, featured agents, custom agents, and all agents. Includes search input, category/subject/LLM/type filters, star/favorite toggle, and "Create Agent" action.

Do NOT add custom styles, colors, or CSS overrides to ibl.ai SDK components. They ship with their own styling. Keep the components as-is. Do NOT implement dark mode unless the user explicitly asks for it.
