feat(resource): add resource type inheritance and polymorphic tool matching
Implement ADR-042 single-inheritance for resource types with polymorphic
tool and handler resolution.
Core changes:
- Add `inherits` field to ResourceTypeConfigSchema, ResourceTypeSpec, and
ResourceTypeModel with chain depth validation (max 5), circular
inheritance detection, and built-in-from-custom guard
- New inheritance.py module (390 lines): resolve_inheritance_chain(),
validate_chain(), is_subtype_of(), resolve_fields(), find_subtypes()
- Wire inheritance into ResourceRegistryService: chain validation on
register_type(), resolve_type_inheritance_chain(), is_subtype_of()
- Add find_tools_for_resource() to ToolRegistry with polymorphic matching
that walks the inheritance chain
- Add resolve_handler_polymorphic() to handler resolver
- Alembic migration m6_004_resource_type_inherits adds inherits column
and index to resource_types table
CLI changes:
- `agents resource type list` shows Inherits column
- `agents resource type show` displays inheritance chain
Tests:
- 30 BDD scenarios in resource_type_inheritance.feature (all pass)
- 18 Robot Framework test cases
- 14 ASV benchmark timing methods across 4 suites
Docs:
- docs/reference/resource_type_inheritance.md (full reference)
- Updated docs/schema/resource_type.schema.yaml
- CHANGELOG entry for #513
ISSUES CLOSED: #513
