- loop_parallel_test.go: four tests covering concurrent execution (barrier
pattern), serial tool breaking a batch, cancellation filling all results,
and nil ClassifyTool falling back to serial
- loop.go: emit "tool" events for all cancelled tool calls (early-ctx-err
path in execOne, top-level ctx check, and post-batch fill) so every
dispatched tool call has a visible result regardless of cancellation timing
- anthropic_stream_test.go: five tests covering tool schema cache_control
placement (last tool only, single-tool edge case) and tool result caching
(large gets cache, small does not, last of multiple large results wins)
