refactor: unify runtime directories and environment variables to HAPI_HOME

Consolidate CLI and server runtime directories from ~/.config/hapi/ (CLI) and ~/.hapi-server/ (Server) to a single ~/.hapi/ directory. Unify environment variables from HAPI_HOME_DIR (CLI) and HAPI_BOT_DATA_DIR (Server) to a single HAPI_HOME variable across both applications. Update all documentation and configuration references accordingly. Bump bun-types to 1.3.5.
