Add `tmuxido --update` command to update binary from latest release.
- New `self_update` module with version comparison
- Atomic binary replacement with backup/rollback
- Fetches latest release from Gitea API
- Downloads correct binary for system architecture
Adiciona módulo `deps` que, antes de qualquer operação, verifica se
fzf e tmux estão instalados no sistema. Caso faltem, detecta o
gerenciador de pacotes da distro (apt, pacman, dnf, yum, zypper,
emerge, xbps, apk), informa ao usuário e oferece instalar com o
comando adequado.
- `src/deps.rs`: Dep, PackageManager, BinaryChecker (trait injetável),
check_missing(), detect_package_manager(), ensure_dependencies()
- `src/main.rs`: chama ensure_dependencies() antes do fluxo principal
- `tests/deps.rs`: 11 testes de integração com SystemBinaryChecker real
- `tests/docker/`: Dockerfile multi-stage + suite de 15 testes em
container Ubuntu 24.04 simulando novo usuário (sem fzf/tmux)
- `.dockerignore`: exclui target/, .git/, .claude/ do contexto Docker
Move scan_from_root, scan_all_roots, get_projects, show_cache_status
and launch_tmux_session from main.rs into a new src/lib.rs, making
them pub so they are testable independently of the binary entrypoint.
main.rs is now a thin entrypoint that imports from tmuxido:: and keeps
only select_project_with_fzf (interactive subprocess, not unit-testable).
Add tempfile = "3" to [dev-dependencies] in preparation for tests.
