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).

+## arch
+Simple procedural seeding scripts with idempotent create-or-update logic using direct database operations, organized as a Python package with one seed module per entity type.
