* Determines if a tool error type should be treated as fatal.
*
* Fatal errors are system-level issues that indicate the environment is in a bad state
* and continued execution is unlikely to succeed. These include:
* - Disk space issues (NO_SPACE_LEFT)
*
* Non-fatal errors are issues the LLM can potentially recover from by:
* - Correcting invalid parameters (INVALID_TOOL_PARAMS)
* - Trying different files (FILE_NOT_FOUND)
* - Respecting security boundaries (PATH_NOT_IN_WORKSPACE, PERMISSION_DENIED)
* - Using different tools or approaches
*
* @param errorType - The tool error type to check
* @returns true if the error should cause the CLI to exit, false if it's recoverable
