// InCode Thread Management Tools Test Suite
// 
// GRANULAR FEATURES TESTED:
// - F0041: list_threads - List all threads with IDs and states
// - F0042: select_thread - Switch to specific thread for debugging
// - F0043: get_thread_info - Get thread details (state, stack, registers)
// - F0044: suspend_thread - Suspend specific thread execution
// - F0045: resume_thread - Resume suspended thread
//
// Tests thread management with real LLDB integration using test_debuggee binary
