Sync Yield from Intelligence Flow @ 4c338abc0d14

[operator-stack-publisher]

What this sync releases

First-party conformance evaluations

• Replace third-party conversion comparisons with 40 owned workflow fixture
  runs across TypeScript, Python, Go, and Rust.
• Add five runtime-invariant checks for resume, replay, divergence, blocking,
  and explicit source migration.
• Publish a source-digested result with an explicit claim boundary: the suite
  verifies Yield's coding and supervision layer, not agent judgment or product
  superiority.
• Rerun the same suite against the source tree and projected public surface in
  CI.
