Subject: [PATCH] test(ai): drop three tests that duplicate surviving
 assertions

Removes 'captures tool calls from stream chunks', 'shows steps only when greater than 1' and 'concatenates tool calls across multiple calls'. Each asserted behavior that is still covered by another test in the same file. Mutation checks against src/ai/index.ts (steps gate, stream tool-input-start, tool-call accumulation) each fail on at least one surviving assertion, so coverage of those paths is unchanged. Test count goes from 103 to 100; no source change.
