Patch Changes

• #2224 dcca089 Thanks @mattzcarey! - Truncate structured results structurally instead of slicing their JSON.

  truncateResult (the default transformResult in Think's execute tool and the browser tools) and the codeMcpServer / openApiMcpServer response path used to pretty-print an oversized object and cut it at a character count, leaving the model with half a JSON document. Oversized values are now shrunk in place, largest values first: strings are clipped with a --- TRUNCATED --- <n> chars suffix, arrays keep their leading items and end with a --- TRUNCATED --- <n> more items element, and an object only loses entries (largest first, named in a "--- TRUNCATED ---" entry) when its values cannot share the budget. The output is always valid JSON of the original shape and small values pass through untouched.

  The Code Mode tool now carries a toModelOutput that projects calls out of what the model sees and bounds the sandbox logs the same way a result is bounded. The durable call log — every connector call's args and result — stays on the persisted tool part for UIs and audit, but no longer rides into the model's context uncapped alongside the transformed result. The projection never throws: a BigInt or cyclic value is rendered rather than failing a completed run at model assembly.

  The MCP servers apply the response budget to the text they emit, pretty-printing only while that still fits.

  Fixes #2009, #2143 and #2182.
