* fix(mcp): deliver tool errors within advertised schema contracts Retain complete typed JSON error content while omitting non-conforming structured errors at the public transport boundary. Recover oversized diagnostics into Evidence before removing their private structured carrier. Update schema-validated client readers and cover actual stdio delivery. Closes #1261 Assisted-by: Kogasa (gensokyo-skills:kogasa-surprise-testing) * test(mcp): read typed errors in canonical Evidence regressions * test(mcp): validate public error diagnostics in acceptance workflows
