Walkthrough

This PR removes caching infrastructure including the utils/cache.py module, cache-related imports and functions from app.py, development startup scripts for both Linux and Windows, and environment variable definitions from .env.example.

Changes

Cohort / File(s)	Summary
Caching Infrastructure utils/cache.py, app.py	Removes entire in-memory cache module with TTL support and decorator functionality. Deletes cache-related imports and functions (initialize_app, refresh_data) from app.py that handled cache invalidation on startup and data refresh.
Development Scripts scripts/linux-dev.sh, scripts/win-dev.bat	Removes both OS-specific development scripts that previously orchestrated background startup of backend server and Tauri frontend processes.
Configuration .env.example	Removes two environment variable definitions (private and public base64 string values).
