- Added new CLI flags: --no-tools, --no-extensions, --no-skills
- Added login dialog, countdown timer, and component barrel export
- Added blockImages and thinkingBudgets settings
- Refactored stdin handling with StdinBuffer for improved key parsing
- Updated DEVELOPMENT.md with new architecture documentation
