mcp-tool-output-offload-threshold-2000-tokens

MCP responses exceeding 2,000 tokens should be offloaded to a temp file with a summary reference returned to context rather than held in-context verbatim. This prevents individual verbose API responses from consuming disproportionate context budget. The pattern is: write full output to /tmp/toolname-TIMESTAMP.json, return ‘Full output at /tmp/…, summary: [3-5 lines]’ to context.
