Codify WebMCP JSON Schema subset (Draft 2020-12) per 2026-03-05 CG resolution.
Meta-validation in registerTool() (TypeError on invalid schema) and input
validation in executeTool() parallel block before tool execute steps
(DataError with {path,reason,schemaPath} for agent self-correction).
Spec-only per review; WPT split to web-platform-tests/wpt (tentative).
Coordinates with webmachinelearning#254 (outputSchema, same dictionaries).

This PR adds an optional
outputSchemamember to theModelContextToolandRegisteredTooldictionaries to enable browser agents and in-page agents to help LLMs reliably reason about the return values of tools.While
responseConstraintwas previously discussed, that name is too specific to the Built-in AI / Prompt API. TheoutputSchemaname aligns directly with the MCP Tools specificationoutputSchemaused to define expected structured outputs with JSON Schema.FIX #9
