Greptile Summary

This PR fixes two targeted regressions introduced by upstream API drift. Both changes are minimal, well-scoped, and do not introduce new logic.

• src/tui/gateway-chat.ts: The call to ensureExplicitGatewayAuth was passing a non-existent property auth (should be explicitAuth) and omitting urlOverrideSource. Without urlOverrideSource: "cli", the function's early-return guard (if (params.urlOverrideSource === "cli" && (explicitToken || explicitPassword)) { return; }) would never trigger, causing the function to throw an error for every CLI URL override — even when valid explicit credentials were supplied. The fix passes the correctly-named explicitAuth property and adds urlOverrideSource: "cli", restoring the intended auth-bypass behavior for credentialed CLI users.
• extensions/synology-chat/src/webhook-handler.test.ts: The local makeReq helper is removed in favour of the identical implementation already exported from test-http-utils.ts (imported on line 4). The two implementations are functionally equivalent, so no test behaviour changes.

Confidence Score: 5/5

• This PR is safe to merge — both changes are minimal, verified against the actual function signatures, and fix clear type/declaration errors without introducing new logic.
• Both changes are straightforward corrections to API mismatch and duplicate declaration issues. The ensureExplicitGatewayAuth fix is verified against the actual function signature in src/gateway/call.ts (lines 87–123); the property rename and the addition of urlOverrideSource: "cli" exactly match what the function expects. The makeReq removal in the Synology test is equally safe — the shared utility is functionally identical, and the import was already present on line 4.
• No files require special attention.

⚠️ Critical Dependency Note
This PR fixes a blocking regression in main (duplicate test helper conflict) that is causing CI to fail across multiple active PRs, including PR #32119.

Merging this PR is a prerequisite for unblocking the CI status of other scoped fixes. Keeping these separate ensures each change maintains the smallest possible scope and is independently verifiable.

⚠️ Note on CI Failure
In addition to the Synology regression, CI is also intermittently failing due to a flake in src/security/skill-scanner.test.ts. A fix for this flake is in PR #32159.

⚠️ Note on CI Failure
Intermittent CI failures are also being caused by a flake in src/cron/isolated-agent.uses-last-non-empty-agent-text-as.test.ts. A fix is in PR #32165.

Closing as recent refactors in main have resolved the immediate CI block. Glad to see the combined stack is now healthy.
