Implement capability generics, checked package specializations and CRUD scaffolding

Add kinded parameters, capability bounds, Self, aliases and closed application identities. Check generic implementations universally and build candidate-specific codecs and descriptors from immutable schemas. Preserve lexical aliases and exact dispatch identities in package and host bindings.

Add an imperative CRUD+index domain scaffold with explicit soft-deletion semantics, source/codegen regression coverage, installed CLI tests and an authoring guide. Existing Web Studio opaque props and class-level create-menu migration are separate from the implemented language core.
