Developer d3a69ad910 fix(mcp): tolerate invalid tool output schemas Closes #26529. When an MCP server returns a tool whose \`outputSchema\` contains a broken \`$ref\` (e.g. Google Stitch's \`#/$defs/ScreenInstance\`), the SDK's typed \`listTools()\` validator throws and opencode marks the ENTIRE server as failed — losing every other valid tool the server exposes. Catch the schema-reference errors and retry with a tolerant schema (\`looseObject\` + \`outputSchema: z.unknown().optional()\`) via the raw \`request\` path so the bad tool's schema is accepted as opaque while the others load normally. Equivalent fix shape to #26530 (nicolascancino) — kept his approach since it's correct. Bundles our reproducer test from \`kit/issue-reproducers\` so the regression is locked in. Verified red → green → red → green: - pre-fix: server marked \`failed\` - post-fix: server stays \`connected\`, valid tool present		2026-05-09 19:00:34 -04:00
