Add Vite plugin that auto-generates TypeScript types from serving endpoint OpenAPI schemas. Includes AST-based server file extraction (@ast-grep/napi), schema-to-TypeScript conversion, and caching. Also adds useServingInvoke and useServingStream React hooks in appkit-ui with full type-safe registry support. Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>
- Store requestKeys[] in serving cache instead of regex-parsing TypeScript type strings in schema-filter (fragile indentation dependency) - Add overrideBody parameter to useServingStream's stream() to allow callers to pass fresh body without waiting for useMemo recomputation - Lazy-init WorkspaceClient in type generator (skip when no endpoints resolve) Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>
Chunks persisted after onComplete, causing the streaming bubble to remain visible alongside the committed message (duplicate response). Now chunks are cleared atomically with setStreaming(false) so React batches all state updates in one render. Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>
Clearing chunks in the hook's .then() handler caused a race with React batching — chunks were empty before the component could commit them. Let consumers decide when to clear via reset() instead. Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>
Without a .catch(), if connectSSE rejects the promise is unhandled and setStreaming(false) never fires, leaving the hook in a broken state. This matches the pattern used by the genie chat hook. Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>

The invoke callback is recreated whenever body changes (via useCallback deps), which triggers the useEffect cleanup that aborts in-flight requests. Adding overrideBody allows callers to use a stable body while passing the real payload per-invocation, matching useServingStream. Signed-off-by: Pawel Kosiec <pawel.kosiec@databricks.com>
