When no git remote is configured, DetectUserRole() now defaults to
Maintainer instead of Contributor. This fixes issue routing for:
1. New personal projects (no remote configured yet)
2. Intentionally local-only repositories
Previously, issues would silently route to ~/.beads-planning instead
of the local .beads/ directory.
