build(deps): bump github.com/modelcontextprotocol/go-sdk from 1.3.0 to 1.3.1

[dependabot]

Bumps github.com/modelcontextprotocol/go-sdk from 1.3.0 to 1.3.1.

Release notes

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

v1.3.1

This release is a patch release for v1.3.0.

It contains a cherry-pick for a security issue reported in #805, which takes advantage of the default behavior of Go's standard library JSON decoder that allows case-insensitive matches to struct field names (or "json" tags). The issue has been addressed by changing the JSON decoder to one that supports case sensitive matching.

Fixes

• all: use case-sensitive JSON unmarshaling by @​maciej-kisiel in modelcontextprotocol/go-sdk#807

New external dependencies

• https://github.com/segmentio/encoding, which is the package that provides the new decoder.

[dependabot]

A newer version of github.com/modelcontextprotocol/go-sdk exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

Closing — the repo is already on github.com/modelcontextprotocol/go-sdk v1.5.1-0.20260403154220-27f29c1cef3b, well past v1.3.1, so this update is obsolete.

[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.
