Align CLI fallback routing warnings

[etbyrd]

Summary

• Make the CLI function test warning helper mirror server routing: same-domain function endpoints suppress fallback function endpoints.
• Update CLI templates and test-function API docs from catch-all terminology to fallback terminology.
• Regenerate OpenAPI API clients/docs for Node, Python, and Go.

Why

Fallback endpoints only receive managed-domain mail when the inbound domain has no enabled domain-scoped endpoint. The old CLI wording and warning logic could imply multiple functions would receive the same test email when server routing would only deliver to scoped endpoints.

Validation

• pnpm --dir cli-node exec vitest run tests/oclif/functions-test-function.test.ts tests/oclif/functions-init.test.ts
• make cli-check
• COREPACK_ENABLE_AUTO_PIN=0 make node-check
• make python-check
• make go-check
• COREPACK_ENABLE_AUTO_PIN=0 make shared-check
• git diff --check

Greptile Summary

This PR aligns CLI warning logic and documentation with actual server routing behavior: when same-domain function endpoints exist for an inbound domain, fallback endpoints are now suppressed in the warning helper, matching what the server would do. All "catch-all" terminology across CLI templates, OpenAPI specs, and generated SDK code (Node, Go, Python) is replaced with "fallback."

• Logic change in findMatchingFunctionEndpoints: endpoints are now bucketed into domain-scoped and fallback lists; domain matches take priority and suppress fallbacks, eliminating misleading multi-function warnings when only one endpoint would actually fire in production.
• Documentation and terminology: the testFunction API description is updated across YAML, JSON codegen, and all generated SDK files to accurately explain scoped vs. fallback domain selection.
• Tests: existing tests are updated to reflect the new suppression behavior, and two new test cases cover the fallback-only and fallback warning-formatting paths.

Confidence Score: 5/5

Safe to merge — changes are a small, well-tested logic fix in the CLI warning helper and a consistent documentation update across generated SDK files.

The routing-suppression logic in findMatchingFunctionEndpoints is straightforward and verified by three test scenarios (domain suppresses fallback, fallback-only, unknown domain). All generated files are consistent with the source YAML. No runtime-affecting code changed outside the CLI warning path.

No files require special attention.

Important Files Changed

Filename	Overview
cli-node/src/oclif/commands/functions-test-function.ts	Core logic change: findMatchingFunctionEndpoints now splits endpoints into domain vs. fallback buckets and returns domain matches when any exist, suppressing fallbacks — correctly mirroring server routing. Terminology updated from "catch-all" to "fallback".
cli-node/tests/oclif/functions-test-function.test.ts	Tests updated and expanded: first test now verifies fallbacks are suppressed when same-domain endpoints exist; two new tests cover fallback-only and warning-formatting scenarios; all expected scopes updated from "catch-all" to "fallback".
cli-node/src/oclif/function-templates.ts	Comment-only update: loop-protection documentation updated from "catch-all" to "fallback" terminology.
cli-node/tests/oclif/functions-init.test.ts	Comment-only updates in test descriptions, replacing "catch-all" with "fallback" for consistency.
openapi/primitive-api.yaml	Documentation update for testFunction operation: replaces "catch-all routing receives identically" with accurate description of scoped vs. fallback domain selection logic.
openapi/primitive-api.codegen.json	Mirrors the YAML description update for testFunction in the codegen JSON artifact.
packages/api-core/src/api/sdk.gen.ts	Generated TypeScript SDK: JSDoc comment for testFunction updated to match revised OpenAPI description.
packages/api-core/src/openapi/openapi.generated.ts	Generated file: inline OpenAPI document string updated to reflect new testFunction description.
packages/api-core/src/openapi/operations.generated.ts	Generated file: operation manifest description for testFunction updated to new fallback-aware wording.
sdk-go/api/oas_client_gen.go	Generated Go client: doc comment for TestFunction / Invoker interface updated to new description in two locations.
sdk-go/api/oas_handlers_gen.go	Generated Go handler: doc comment for handleTestFunctionRequest updated to new description.
sdk-go/api/oas_server_gen.go	Generated Go server: Handler interface doc comment for TestFunction updated to new description.
sdk-go/api/oas_unimplemented_gen.go	Generated Go unimplemented stub: doc comment updated to new description.
sdk-python/src/primitive/api/api/functions/test_function.py	Generated Python SDK: docstring for test_function updated to new fallback-aware description.
