Module command 

Shared command execution abstraction.

This module is the single home for synchronous, capture-only command execution in Pacsea. It provides the CommandRunner trait for dependency-injected execution, the production SystemCommandRunner, the run_capture convenience wrapper, and the binary_available capability probe.

Interactive, PTY-based, and terminal-spawning command paths (installs, privilege escalation, clipboard, browsers) intentionally do not go through this module.
