release notes

## GitHub MCP Server gets a touch of gloss :nail_care: 
For clients that support icons (part of the newest MCP specification) we now provide them:


Main Features
🎨 Octicon Icons for Tools, Resources, and Prompts
MCP clients that support the new icons specification will now display GitHub's Octicon icons alongside tools and resources, making it easier to identify capabilities at a glance.
🏗️ Inventory Pattern Architecture
A new internal architecture introduces the Inventory pattern with builder, filtering, and per-request optimization. This lays groundwork for better performance and configurability, especially for remote server deployments.
🚩 Feature Flag Support & Consolidated Actions Toolsets
Added infrastructure for feature flag-based tool enablement, plus a consolidated actions toolset for better organization of GitHub Actions-related tools gated by a feature flag.

--features  cli flag or GITHUB_MCP_FEATURES via ENV.

🔧 Bug Fixes

Fixed create_or_update SHA failures - Resolved issues where file updates could fail due to SHA mismatches
Path parameter now optional - Fixed incorrect required parameter validation

📚 Documentation

New Antigravity installation guide
New tool renaming guide for handling deprecated tool names
