chore: track all project map and index files

Add generated .pi-map.md and .pi-map.index.md files across the repository
so the project navigation maps are shared and versioned. These artifacts
are maintained by project_map_init/patch/validate and must be kept in
sync with source edits.

Note: .cache/ remains ignored (added in previous commit).

+- proposal.md | Proposes architectural changes to externalize Authentik/domain configuration to environment variables and add Traefik reverse proxy deployment support.
+- tasks.md | A task tracking document for externalizing authentication/domain configuration, creating Traefik deployment, updating frontend config, and running verification tests.
+## arch
+Specification-driven development using OpenAPI metadata, with task-driven implementation planning focused on environment-based configuration externalization and reverse proxy integration patterns.
