Summary

• change table/column lookup to load and resolve models before searching them
• compose every manifest role/environment stack, treat the ordered -layer list as one model, and load every dump file as an independent node model
• load independent models through a bounded 32-worker pool while preserving deterministic result order, allowing all 30 nodes in a typical cluster to load concurrently
• search final resolved table columns so inheritance, patches, modifications, overrides, and drops are reflected
• return each matching manifest, layer, or dump model in text and JSON output and update the public documentation

End-to-end coverage

• run the CLI in a subprocess for the multi-table/multi-column report, empty-success behavior, and malformed-input failure
• run the CLI in a subprocess against 30 real node dump files and verify all 30 resolved model references
• use a worker barrier test to prove 30 loads start concurrently before any finishes and that results retain source order

Verification

• go test ./... (1360 tests)
• go test -race ./internal/... ./cmd/... (1346 tests)
• go vet ./...
• go build ./...
• gofmt -s -l .
• git diff --check

Follow-up to #234.
