v0.5.9 — Observable Review Lifecycle

Highlights

• Adds structured text|jsonl lifecycle progress events for Plan, Native, Restricted, recovery, finalization, and publication.
• Preserves Native Review semantics: no prompt injection and no provider-output parsing.
• Keeps stdout result contracts unchanged; progress is advisory on stderr.
• Enables an upper Service layer to report the current review phase on a five-minute cadence.

This release improves review observability and perceived responsiveness; it does not claim to reduce provider execution time.
