Module guardrails 

Pre-transaction guardrails: pacman db-lock detection, disk-space checks, and sync-database freshness checks with actionable guidance.

These checks run before install/remove/update transactions (CLI and TUI) and are read-only: they never mutate the system and are therefore safe in dry-run mode.
