- Added abort signal support to MCP server connection and tool listing operations, enabling cancellation via Escape key during testing.
- Enhanced MCP connection timeout handling with improved abort signal integration in the withTimeout function to prevent race conditions.
- Improved MCP test command UI to display '(esc to cancel)' indicator and handle cancellation gracefully.
- Updated HTTP transport session termination to include timeout mechanism preventing indefinite hangs.
- Fixed MCP test command cleanup to prevent resource leaks when operations are cancelled or aborted.
- Added MCPRequestOptions interface with signal property for request cancellation via AbortSignal.
- Added abort signal support to MCP tool execution enabling request cancellation via Escape-to-interrupt or other abort mechanisms.
- Enhanced MCP request handling with abort signal propagation through HTTP, SSE, and stdio transports with proper cleanup.
- Improved stdio transport request handling to use Promise.withResolvers for cleaner async flow and better abort signal integration.
- Updated HTTP transport to combine operation abort signals with timeout signals using AbortSignal.any() for unified cancellation.
- Modified SSE response parsing to support abort signals and distinguish between timeout and user-initiated cancellation.
- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome.
- Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'.
- Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock.
- Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters.
- Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.
