0.29.0

Added

• Source ess/7 declares command-local replays: a retry returns the originating
  success's typed result and preserves its original subject. An effect-free named
  error can cover the remaining finite subject states. Ordinary wrong_state
  witnesses in this source version observe the complete subject and reject every
  direct event. Earlier source contracts and generated bytes remain unchanged.
• Conformance suites 12 and 13 capture actual original results, input, actor
  and identity before an unforced retry. Rust and generated Go compare exact
  typed responses and fresh complete subject observations. Native adapters retain
  exact integers; JSON adapters must preserve declared Integer values before
  observation or refuse. Decimal/Binary64 response positions remain unsupported.
  TypeScript/browser readers refuse these suite envelopes before callbacks.
• Complete snapshots carry a finite typed row descriptor and validate both
  observations before comparison. Missing required fields cannot pass as an
  unchanged partial row. Replay synthesis checks the retry's own eligibility
  against the original input and post-command subject; unavailable immediate
  witnesses receive a named refusal.
• Native Rust/Go outcomes retain the typed response even without an event mapping.
  Documentation, OpenAPI, AsyncAPI and the compiled graph expose the replay
  relation; ess-diff/6 records replay origins and complete-refusal observation
  changes. The generated source schema includes the new declaration.

The generated witness covers an immediate retry. Persistence, restart, later-head
retries and absence of physical writes remain adopter-owned acceptance.
