The ports package was fully implemented but detect_openbsd.go still returned nil candidates with a stale TODO. Wire up ports.New() so OpenBSD systems can auto-detect their package manager. Also adds: - Unit tests for GetCapabilities with mock managers (base + full) - Unit tests for Locker mutual exclusion - Edge case tests for ports parser (empty input, whitespace, fallback) - Minor dep updates (charmbracelet/ultraviolet, charmbracelet/x)
