feat(sdk): TypeScript SDK — scaffold + core client - #99
Merged
Conversation
A thin @riskkernel/sdk mirroring the Python SDK over the /v1 API: Runtime, governedRun, Budget, and Run (step / checkpoint / cancel / status / proxyConfig / approve), with the 402 -> BudgetExceeded mapping. Dependency-free (global fetch, Node 18+), dual ESM/CJS build via tsup, vitest tests against an in-process mock daemon, and a path-filtered CI workflow. Verified end-to-end against the real daemon: a governed run with a loop budget halts with loop_budget_exceeded. Crash-resume, framework adapters, and npm publishing are left as tracked contributor issues (#80-#82).

The TypeScript/JavaScript SDK (#27), scaffolded with a working core client — the npm-ecosystem analog of the Python SDK.
