feat: witryna 0.2.0HEADv0.2.0main

Switch, cleanup, and status CLI commands. Persistent build state via
state.json. Post-deploy hooks on success and failure with
WITRYNA_BUILD_STATUS. Dependency diet (axum→tiny_http, clap→argh,
tracing→log). Drop built-in rate limiting. Nix flake with NixOS module.
Arch Linux PKGBUILD. Centralized version management.
