Tools annotated with "# ollie:parallel read" now run concurrently when
the LLM issues multiple such calls in a single round, without needing
an execute_code pipeline.
- tools.ParallelClassifier interface; execute.Server implements it via
IsParallelRead, which reads the tool script and checks the annotation
- BuildAgentEnv wires IsParallelRead → AgentEnv.classifyTool →
agentConfig.ClassifyTool (nil when execute server absent)
- loop.go: consecutive parallel-safe calls are fanned out with a
WaitGroup; results are collected in submission order; cancellation
fills remaining calls with interrupted results; serial tools and
batches of one skip the goroutine overhead
