This PR implements comprehensive GitHub Projects and Issues Management tools for the MCP server, enabling intelligent and automated project planning, backlog grooming, and issue lifecycle management through context-aware automation.

🚀 Key Features Added

GitHub Projects v2 Integration (GraphQL)

• list_projects_v2: List Projects v2 for organizations or users with full metadata
• get_project_v2: Get detailed project information including custom fields
• get_issue_node_id: Convert issue numbers to node IDs required for Projects v2 operations
• add_issue_to_project_v2: Add issues to Projects v2 for automated workflow management

Enhanced Issue Management

• list_milestones: List repository milestones with state filtering (open/closed/all)
• create_milestone: Create milestones with optional descriptions and due dates
• Enhanced existing issue toolset with milestone management capabilities

🔧 Technical Implementation

New Toolset

• Added projects toolset with proper read/write tool categorization
• Enhanced issues toolset with milestone management tools
• Follows existing codebase patterns for GraphQL integration

Core Changes

• pkg/github/projects.go: New file implementing Projects v2 tools using GraphQL API
• pkg/github/issues.go: Added milestone management functions
• pkg/github/server.go: Added RequiredInt64 helper for parameter validation
• pkg/github/tools.go: Integrated new toolsets into the main toolset group

Quality Assurance

• Comprehensive test coverage with toolsnaps validation
• All existing tests continue to pass
• Updated README documentation with tool descriptions and parameters

💡 Usage Examples

# List organization's Projects v2
list_projects_v2(owner="myorg", owner_type="organization")

# Get issue node ID for Projects v2 operations  
get_issue_node_id(owner="myorg", repo="myrepo", issue_number=123)

# Add issue to Projects v2
add_issue_to_project_v2(project_id="PVT_kwDOABCD...", issue_id="I_kwDOABCD...")

# Create milestone with due date
create_milestone(owner="myorg", repo="myrepo", title="v2.0", due_on="2024-12-31T23:59:59Z")

🎯 Benefits

• Context-aware project management: Natural language integration with GitHub Projects v2
• Automated issue triage: Easy assignment of issues to projects and milestones
• Sprint/milestone coordination: Streamlined milestone creation and management
• Multi-repo project support: Organization and user-level project management
• GraphQL-powered: Leverages modern GitHub Projects v2 API for advanced automation

This implementation enables the core functionality requested in the issue: natural language and model-driven project/issue interactions, programmatic control over GitHub Projects, and automated issue lifecycle management.
