WebUI 'Recent projects' limited to 5, no way to see all projects #7877

Summary

The WebUI homepage only displays 5 most recently accessed projects. There's no way to view or access other registered projects through the UI.

Problem

• Projects are stored in ~/.local/share/opencode/storage/project/*.json
• WebUI "Recent projects" section only shows 5 projects (sorted by updated timestamp)
• If user has more than 5 projects, older ones become inaccessible via UI
• No "Show all projects" option or project browser exists

Reproduction

1. Register 6+ projects (by accessing them or creating storage JSON files)
2. Open WebUI homepage
3. Only 5 projects visible

Expected Behavior

• Either increase the limit or remove it entirely
• Or provide a "View all projects" option
• Or add a project browser/search feature

Environment

• OpenCode version: latest
• Running in Docker container

Workaround

Manually update the updated timestamp in project JSON files to rotate which projects appear.
