* test(mcp): update test to expect signal parameter in createFlow

fix(agents): include 'new' conversationId in newConvo check for title generation

When frontend sends 'new' as conversationId, it should still trigger
title generation since it's a new conversation. Rename boolean variable for clarity

fix(agents): check abort state before completeJob for title generation

completeJob now triggers abort signal for cleanup, so we need to
capture the abort state beforehand to correctly determine if title
generation should run.
