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).

+Specification-driven requirements document using scenario-based behavioral specification with clear separation between failure domains (tunnel vs. application), state-based recovery actions, and conditional UI response patterns.
