v0.3 changelog

Added

• Typed descriptor schemas for v0.3 manifest fields.
• overlayTemplates for tenant / workspace / user / customer customization.
• SDK typed-call expectations and stable runtime semantics.
• Package-level packageHash in projection provenance.
• Reference APP 内容工厂 / content-factory-app fixture.

Changed

• scene and home entries are compatibility-only and invalid for manifestVersion 0.3.
• Reference CLI now checks entry-specific required fields and warns when product-level apps lack runtime packages or permissions.
• Current docs frame Agent App as executable standard, not only installable package metadata.

Compatibility

• v0.1 and v0.2 documents remain in versioned docs.
• Legacy manifests can still be read by the reference CLI, but current v0.3 manifests should not use legacy entry kinds.
