fix: Correct package name for sequential thinking server

[Hunter-Houts]

Description

This PR fixes an inconsistency in the package naming for the sequential thinking server. The root package.json was referencing @modelcontextprotocol/server-sequentialthinking while the actual package name uses hyphens @modelcontextprotocol/server-sequential-thinking. This inconsistency was causing npm install errors.

Server Details

• Server: sequential-thinking
• Changes to: package configuration and naming

Motivation and Context

When running npm install in the sequential thinking server directory, it fails with a 404 error because npm is looking for a non-existent package name (without hyphens). This fix ensures consistent naming across all package references, allowing proper installation and workspace configuration.

Error being fixed:

npm WARN workspaces @modelcontextprotocol/server-sequential-thinking in filter set, but no workspace folder present
npm ERR! 404 Not Found - GET https://registry.npmjs.org/@modelcontextprotocol%2fserver-sequentialthinking

How Has This Been Tested?

• Verified npm install works correctly after the name change
• Confirmed workspace configuration recognizes the package
• Tested package binary name functionality

Breaking Changes

No breaking changes. This is a fix for an existing issue that prevented proper installation.

Types of changes

• Bug fix (non-breaking change which fixes an issue)

Checklist

• I have read the MCP Protocol Documentation
• My server follows MCP security best practices
• My code follows the repository's style guidelines
• I have added appropriate error handling

Additional context

The change ensures consistent naming convention across the monorepo:

1. Changed in root package.json:

   - "@modelcontextprotocol/server-sequentialthinking": "*"
   + "@modelcontextprotocol/server-sequential-thinking": "*"

2. Verified package.json in src/sequentialthinking maintains hyphenated naming:

   {
     "name": "@modelcontextprotocol/server-sequential-thinking",
     "bin": {
       "mcp-server-sequential-thinking": "dist/index.js"
     }
   }
