Orbit v0.12.0 (Preview)

What changed

Orbit environments can now inherit from one parent file with extends:. Mapping keys merge recursively while scalar and list values are replaced. Parent and child schema errors preserve their authored file and line, and missing parents surface as stale after transient-save protection.

The bundled quickstart and agent plugin are paired with this release.

Why it matters

Teams can maintain E2E and CI variants without copying hundreds of lines of shared environment configuration. Errors still point to the file authors need to fix, and running environments notice when a shared parent changes or disappears.
