This release improves MCP catalog server management, fixes streaming issues with AI providers, and adds memory protection for file search operations.

What's New

• Adds --json flag to alias list command for structured output
• Adds ContextLimit helper to modelinfo for centralized context window handling
• Blocks enable_remote_mcp_server until the server is actually connected, eliminating the need to re-ask questions

Improvements

• Removes command queueing - commands are now sent immediately
• Removes empty query truncation from MCP server search, showing all matching servers
• Restricts MCP catalog to OAuth and anonymous-access servers only, removing API key complexity

Bug Fixes

• Fixes Gemini parallel tool responses by coalescing them into a single Content
• Fixes custom OpenAI provider routing for Responses-only models (gpt-4.1, o-series, gpt-5, Codex)
• Fixes memory explosion in search_files_content by capping output at 1 MiB and skipping large files
• Fixes MCP catalog retry logic for existing unstarted entries
• Fixes rollback behavior when MCP server Start is cancelled during OAuth or Tools operations
• Fixes conversation caching to exclude failed chat continuations

Technical Changes

• Refactors registry operations to reuse single session across digest and pull operations
• Updates OpenAI handler to support newer Responses stream event shapes
• Uses cmd.Context() instead of context.Background() for proper cancellation support
• Uses strings.Builder for message merging to reduce memory allocations
• Improves search_files_content memory handling for symlinks and device files
