Transient errors can occur when attaching to a process that is actively using thread delegation (e.g. asyncio.to_thread). Add a retry loop to _get_awaited_by_tasks for RuntimeError, OSError, UnicodeDecodeError, and MemoryError, and expose --retries CLI flag on both `ps` and `pstree` subcommands (default: 3).
Silent retries are less confusing; only report on final failure.

Error path working too
I also fixed error paths to write to stderr, not stdout (I know this was copied over from pdb), hope you don't mind (should be small enough).
