fix: restore legacy /projects/projects endpoint for older CLI versions

Older versions of basic-memory CLI (v0.17.4 and earlier) call
GET /projects/projects to list projects. This endpoint was removed
when we migrated to v2 routers.

Add explicit route at /projects/projects (without trailing slash) to
avoid 307 redirects that the cloud proxy doesn't follow.
