Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the changelog for the v0.33.0-preview.0 release of the Gemini CLI. It incorporates the latest features and improvements across Plan Mode, agent capabilities, CLI user experience, and core architectural enhancements, ensuring the documentation reflects the most current state of the application.

Highlights

• Plan Mode Enhancements: Added support for annotating plans with feedback for iteration, enabling built-in research subagents in plan mode, and a new 'copy' subcommand.
• Agent and Skill Improvements: Introduced the new 'github-issue-creator' skill, implemented HTTP authentication support for A2A remote agents, and added support for authenticated A2A agent card discovery.
• CLI UX/UI Updates: Redesigned the header to be compact with an ASCII icon, inverted the context window display to show usage, and directly indicated auth required state for agents.
• Core and ACP Enhancements: Implemented slash command handling in ACP (for '/memory', '/init', '/extensions', and '/restore'), added a set models interface to ACP, and centralized 'read_file' limits while truncating large MCP tool output.
