I don't understand this change.
- Upgrade @modelcontextprotocol/sdk from ^1.17.1 to ^1.26.0 to fix GHSA-345p-7cg4-v4c7 (cross-client data leak vulnerability) - Upgrade zod from ^3.x to ^4.x for SDK compatibility - Replace zod-to-json-schema with Zod 4's built-in z.toJSONSchema() - Update code for Zod 4 API changes (z.record requires key schema) - Update code for SDK 1.26.0 API changes: - Use AnySchema/SchemaOutput types from zod-compat - Add assertTaskCapability/assertTaskHandlerCapability methods - Use safeParse for cross-Zod-version compatibility - Update tests for SDK behavioral changes: - Tool errors now returned as results with isError: true - Remove deprecated toolDefinition field from tests � Conflicts: � packages/audit-hook/package.json � packages/custom-description-hook/package.json � packages/explain-hook/package.json � packages/fetch-docs/package.json � packages/guardrail-hook/package.json � packages/hook-common/package.json � packages/local-tools-hook/package.json � packages/local-tools-hook/src/hook.test.ts � packages/local-tools-hook/src/hook.ts � packages/passthrough-mcp-server/package.json � packages/passthrough-mcp-server/src/integration-tests/continueAsync.integration.test.ts � packages/passthrough-mcp-server/src/integration-tests/error-callbacks.integration.test.ts � packages/passthrough-mcp-server/src/protocol/passthroughBaseProtocol.ts � packages/server-hook/src/hook.test.ts � packages/simple-log-hook/package.json � packages/whoami-server/package.json � pnpm-lock.yaml � test/integration/package.json � test/integration/servers/api-key-protected/package.json � test/integration/servers/echo/package.json � test/integration/servers/local-stdio/package.json
