[0.5.1] - 2026-09-06

Release recovery: v0.5.0 failed its tag-trigger release gate before any
npm/GitHub Release publication (release workflow 34036439113 failed at
pnpm test because tests/e2e/chain-composition.test.ts asserted the
absence of v0.5* tags — impossible on the exact tagged checkout the
workflow validates; npm v0.5.0 was never published and no GitHub Release
v0.5.0 was created). The immutable v0.5.0 tag is preserved untouched
as the failed-release marker. v0.5.1 contains the intended v0.5 feature
set plus the release-context test correction.

Fixed

• Chain-composition proof (tests/e2e/chain-composition.test.ts) no
  longer asserts tag absence or hard-coded published-stable versions; it
  proves status/projection parity (CLI ≡ SDK ≡ MCP ≡ Action),
  verification-bound handoff round-trip, and completion — identically on
  untagged and tagged checkouts. Release lifecycle assertions live in
  the release/version contract tests.
• New regression (tests/contract/release-tag-context.test.ts) proves
  release/tagged-checkout execution cannot fail merely because the
  triggering release tag exists (fixture repository carries a
  release-shaped tag through status parity, handoff, and completion).
