+Add experimental SWE-Pruner support (disabled by default). When enabled via `experimental.swe_pruner` or the Experimental settings tab in VS Code, the read and grep tools accept an optional `context_focus_question` parameter; when the agent provides it, large tool outputs are pruned by a small model down to the lines relevant to that question, with omitted sections marked inline. Any pruning failure falls back to the full output.
