Show Epic status

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 epic status [EPIC-KEY] --json.
2. Run singularity-flow epic report [EPIC-KEY] --format json.
3. Show the four planning phases or selected full-delivery profile as an arrow flow.
4. For every Story show plan ID, Jira key, repository, canonical/child branch, Jira observation, workflow percentage, submission, required checks, conformance, blockers, duration, model, tokens, and cost availability.
5. Label Jira drift, stale sources/specifications, configured-local Git identity assurance, and self-approval honestly.
6. End with singularity-flow epic next [EPIC-KEY] --json. Do not mutate lifecycle state.
