VersionedSchema proposal: ee7ab8096f

Proposal packages built from jpowersdev/effect@ee7ab8096ffe96ef15bb46a33b41899afc66e0b7.

These are experimental packages for the VersionedSchema examples, not an official Effect release. All four packages were built together from that commit with internal declarations stripped, the repository JSDoc codemod applied, and the full root build completed. Package manifests use 4.0.7-versioned.ee7ab8096f to identify this snapshot.

The source pin and SHA-256 hashes are recorded in snapshot.json; SHA256SUMS is attached. The examples pin direct and transitive Effect packages to these artifacts and verify their behavior with pnpm test.
