v0.5.1

A usability and hardening pass: make the dashboard legible on first run, scope MCP setup to the project it belongs to, and close two local-attack surfaces.

Added

• First-run onboarding banner under the header: the 3-minute interactive tour, a one-click sample project, and the guide. Persists per browser and retires once the tour is completed or dismissed.

Changed

• Project-first navigation. The header surfaces a single destination, Projects. The MCP playground moved to a per-project page (/projects/[id]/mcp), reached from an MCP button on the project header, auto-scoped to that project. The old /mcp redirects to the project list.
• Plainer first-run copy and clearer empty states on the Projects and Features lists.
• Human-facing docs no longer use em dashes.

Fixed

• MCP page load time. get_project_aggregate loads features concurrently (was N+1 sequential), tool examples stream in off the main thread, and JSON is formatted only on expand. Skeleton/spinner loaders instead of a blank page.

Security

• DNS-rebinding / CSRF hardening on the default loopback dashboard (always on): loopback Host + same-origin Origin required, rebinding pages fail closed with 403.
• Path-traversal fix on bundle import: ../ in bundle ids can no longer escape the snapshot tree; malformed bundles are rejected with 400.
