build(deps): bump github.com/modelcontextprotocol/go-sdk from 1.6.0 to 1.6.1

[dependabot]

Bumps 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.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
