[codex] Extract Platform consumer kit helpers

[haasonsaas]

Summary

• expose Platform Consumer Kit helpers from the published JS SDK
• add service endpoint/header builders and a reusable consumer conformance scorecard
• update Kestrel consumer bootstrap to use the SDK helpers for Platform headers and service base URLs

Related

• Starts platform-consumer-kit: extract Kestrel's EvalOps integration pattern #57

Validation

• npm --prefix sdk/js run build
• npm run build
• npm --prefix sdk/js run pack:dry

Notes

• npm run test was rerun after npm run contextkit:build; contextkit pipeline and meeting detection passed, but the existing audio data size test failed on local WAV duration reporting (Duration > 3s (got 0.0s)) despite mic buffers and WAV byte size. This appears unrelated to the TypeScript consumer-kit path.

PR Summary

Medium Risk
Moderate risk because it centralizes and changes how Platform request headers and service base URLs are built, which can affect auth scoping and routing if defaults/mappings are wrong.

Overview
Adds a Platform Consumer Kit to the JS SDK, including typed endpoint/config builders (e.g. buildEvalOpsConsumerClientConfig, buildEvalOpsServiceBaseUrls, buildEvalOpsConsumerHeaders) plus a reusable conformance scorecard via scoreEvalOpsConsumerConformance and EVALOPS_CONSUMER_CONFORMANCE_CHECKS.

Updates the Kestrel main-process EvalOps client bootstrap to use these shared builders (including adding agent/trace header support) and expands tsconfig.node.json to compile the SDK TS sources. Documentation is updated with usage examples for the new helpers.

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Token cleaning incorrectly strips trailing slashes
  • The SDK now trims tokens with a dedicated string cleaner so trailing slashes are preserved while URL cleanup remains unchanged.
