Harvested from PR #2732 by @aboimpinto. Parse pausable frontmatter for custom slash commands, add a narrow engine pause gate before tool execution, and preserve paused command state across separate messages until explicit resume, cancel, terminal completion, or a new command. Also centralize strict resume-message detection with negative coverage for deferred or negated phrases, and keep rollback/stash/worktree mutation behavior out of this slice.
