Codex Rescue 0.1.0 Alpha 5

Experimental local-first Alpha5 prerelease. Includes projection and discovery diagnostics, conservative schema and lifecycle evidence, standalone native binaries, thin npm platform packages, and exact-source release verification. Rescue preserves source rollouts and SQLite state, keeps salvage forked, does not replay unknown side effects, and does not claim to repair upstream transport, Desktop/UI, remote/mobile hydration, or persistence failures. See CHANGELOG.md and docs/alpha5-field-validation.md for scope and limitations.
