Restore dynamic dws schema on top of upstream static-endpoint runtime
(v1.0.52) without re-introducing service discovery:
- port schema runtime (runtime_schema/schema_catalog/schema_agent_metadata/
schema_hints) + embedded agent & interface metadata + ir data structures
- ir/catalog.go: drop discovery-dependent BuildCatalog, keep runtime types
- canonical.go NewSchemaCommand: build schema from the live Cobra tree via
runtimeSchemaPayload instead of the stub
- add schema_support.go and design doc docs/schema-dynamic-endpoint-design.md
go build ./... passes; go test ./... 44 packages pass (only unrelated
post-goreleaser packaging tests fail with a known tar format issue).
