Bumps the mcp group with 1 update: github.com/modelcontextprotocol/go-sdk.

Updates github.com/modelcontextprotocol/go-sdk from 1.6.0 to 1.6.1

Release notes

Sourced from github.com/modelcontextprotocol/go-sdk's releases.

v1.6.1

This release adds an MCPGODEBUG flag to opt out of the Content-Type check on POST requests.

Behavior Changes

Prior to v1.6.0 (v1.4.0...v1.5.0), the Content-Type check on POST requests was gated by the same disablecrossoriginprotection MCPGODEBUG flag as the cross-origin protection. In v1.6.0, the cross-origin protection was disabled by default (replaced by the opt-in enableoriginverification flag), but the Content-Type check was kept on unconditionally, leaving no way to disable it. This release restores an escape hatch for both the Streamable HTTP and SSE transports: setting MCPGODEBUG=disablecontenttypecheck=1 skips the Content-Type: application/json validation on POST requests. See #957.
