Show the approval chain

Output contract: Relay requested CLI fields or output faithfully; preserve warnings/errors and only the explanations required below. For suggested actions, pair Shell with the returned Copilot command; honor commandGuidance. If absent, say "Copilot: no verified equivalent"; never invent a slash command.

Boundary: no Story required; cwd=opened Git root or verified repositoryPath from singularity-flow workspace current --json; refuse if neither resolves; never search $HOME/parents.

1. Run singularity-flow approvals $ARGUMENTS --json.
2. Show every phase, governed document, required authority group, approval threshold, recorded reviewer identity, decision, and current wait state.
3. Preserve self-approval and identity warnings exactly.
4. This skill is read-only. Offer /sf-inbox to select pending review work and /sf-approve or /sf-reject only when the user explicitly wants to decide.
