Add shorter entrypoints for the three JSON interoperability examples:

go run ./interop_indexes
go run ./interop_indexes/struct_key_example
go run ./interop_jsondb

The original examples paths and their main.go files still work. Each old and new entrypoint is a thin wrapper around one internal implementation. The example bodies, data locations, output and error behavior are preserved. The secondary-index README now names the real command paths instead of the nonexistent interop_secondary_indexes directory.

Validation:

• GOWORK=off builds all six original/short package paths and their explicit main.go entrypoints against the published sibling-module versions.
• The original and short commands run in separate temporary directories. Their output matches after normalizing generated UUIDs only.
• Both indexed examples read back 500 records and verify category-ascending, price-descending order. The JSON document example verifies the expected person record after its write/read round trip.
• Targeted go vet, gofmt and git diff --check pass.
• New Linux and macOS PR checks run the same consumer build and behavior-parity script.

No module versions, workspace configuration or root documentation changed. This PR does not publish a release or change @latest instructions.

Thanks,
Gerard
