- Added abort signal support to LSP file operations (ensureFileOpen, refreshFile) enabling cancellation of long-running file operations.
- Added abort signal propagation through LSP request handlers (definition, references, hover, symbols, rename) with $/cancelRequest notification support.
- Added shouldBypassAutocompleteOnEscape callback to custom editor allowing parent components to override escape key handling behavior.
- Changed escape key handling in custom editor to respect bypass callback, enabling global escape handling during active operations.
- Fixed LSP operations to properly handle abort signals and throw ToolAbortError when operations are cancelled, with input controller bypassing autocomplete during streaming/loading states.
