Bumps @modelcontextprotocol/sdk from 1.31.0 to 1.32.0.

Release notes

Sourced from @​modelcontextprotocol/sdk's releases.

1.32.0

Upgrade notes

• Redirects: the HTTP client transports now follow a redirect only when it stays on the same origin (same scheme, host and port; http to https on the same host is allowed). A deployment whose endpoint redirects to another host or port either configures the final URL or sets redirectPolicy: 'follow' on StreamableHTTPClientTransport or SSEClientTransport. In browsers, a redirected request fails unless that option is set.
• New options, both off unless you set them: maxToolInputElements on McpServer limits the number of array elements and object members in a tool call's arguments. expectedResource on requireBearerAuth accepts only tokens issued for this server (the token's audience).

PR Summary

Low Risk
Routine dependency-only bump with no code changes; main behavioral delta is stricter MCP HTTP redirects, which only matters if server tests or Claude Agent SDK MCP clients rely on cross-host redirects.

Overview
Bumps the apps/server devDependency @modelcontextprotocol/sdk from 1.31.0 to 1.32.0 and refreshes pnpm-lock.yaml so the resolved version (including under @anthropic-ai/claude-agent-sdk) matches.

There are no application source changes—only the version pin and lockfile. 1.32.0 tightens default HTTP client redirect behavior (same-origin only unless redirectPolicy: 'follow'), plus optional server/auth options that stay off unless configured; nothing in this repo opts into those new settings.
