Returns the details for a release step, including a data field whose shape depends on the step archetype:

• releaseCandidate: RC build info (status, integration IDs).
• approvals: metadata/screenshots approval state via approvalItems.
• takeoff: info about store release — submittedAt, startedReviewAt, approvedAt, markedRejectedAt, releasedAt, plus the precomputed waitingForReviewSeconds (queued before review started) and timeInReviewSeconds (under review).
• regressionTesting: regressionItems and testRuns from the connected regression integration.
• featureReadiness: work items tracked for the release, including project management ticket info and pull request / code review (PR / CR) info.
• rollout: releaseAdoptionRate, phasedRelease (rollout percentage via userFraction, state, dayNumber, startDate), appStoreReviewData (average rating, total ratings count, surfaced user review issues), and monitoringStatistics (crash-free users, crash-free sessions, custom metrics — each with currentValue, delta, previousValue, monitoringMetricStatus).
• Other archetypes: data may be null.

For apps on Flightpaths, stepId resolves to the release's step with that archetype. If the release has more than one step with that archetype (e.g. one per destination), the request fails with the matching step config IDs; use GET /app/{appId}/stepConfig/{stepConfigId}/release/{releaseId}/stepRun instead.
