OLS-3634: ask command with SSE streaming - #2014
Conversation
Implements the core ask command and SSE streaming client for oc-ols. Users can query OLS from the terminal with 'oc ols "question"' or 'oc ols ask "question"'. - cli/ask.go: AskOptions with Complete/Validate/Run, token extraction from JSON payloads, referenced documents displayed on stdout - cli/streaming.go: SSEClient with HTTP transport, SSE parser for lightspeed-service JSON envelope format, idle timeout (120s), HTTP status error mapping (401/403/413) - cli/types.go: LLMRequest, SSE event data types (start, token, end), sseEnvelope with json.RawMessage for numeric precision - cli/root.go: default mode dispatch (unrecognized args -> ask), ask registered as explicit subcommand - cli/kubeconfig.go: improved error message for missing kubeconfig using clientcmd.IsEmptyConfig() - 63 Ginkgo specs across unit and integration tests - Verified against live OLS cluster

Inline comments:
In `@cli/ask.go`:
- Around line 106-114: Wrap the context selected in Run with context.WithCancel,
defer cancel() before invoking client.StreamQuery, and pass the derived context
to it. Preserve the existing fallback to context.Background() and ensure
cancellation occurs on every Run exit, including early returns.
In `@cli/streaming_test.go`:
- Around line 386-394: Update the “resets timeout on successful reads” test
around newIdleTimeoutReader to use a source that emits multiple chunks, with
each read occurring within the one-second idle timeout while the overall
sequence exceeds that timeout; assert that all expected bytes are consumed and
no read error occurs, ensuring timer reset behavior is exercised.
In `@cli/streaming.go`:
- Line 97: Update the request flow around ResolveEndpoint to validate the
resolved endpoint with ValidateEndpointURL before constructing or sending the
HTTP request, ensuring insecure HTTP endpoints are rejected before the
Authorization header is applied.
