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).

+## files
+- .openspec.yaml | Defines an OpenSpec configuration file with schema type and creation date metadata
+- proposal.md | Proposes a structural refactoring to split monolithic frontend pages and backend routers into thinner orchestrators with extracted components/services, restoring a thin-page/thin-router/fat-component pattern. | dep: React components, FastAPI routers, WebSocket, Docker, git services
+- spec.md | A specification document defining a pure structural refactoring to split monolithic frontend pages/backend routers and CSS into smaller, focused components and services without changing any behavior or API contracts. | dep: React, CSS Modules, WebSocket, FastAPI/Flask routers, TypeScript, Vite
+- tasks.md | A phased task list for refactoring a full-stack application by extracting monolithic backend routers and frontend pages/components into modular structures, plus reorganizing CSS into a maintainable architecture. | dep: FastAPI, React, TypeScript, Vite, CSS Modules, WebSocket, py_compile, tsc, npm
+## arch
+Documentation-driven specification pattern using phased task breakdown with OpenSpec metadata tracking, enforcing a thin-page/thin-router/fat-component architecture while preserving zero behavioral changes.
