With break_on(:throw) (bp on throw), the debugger stops at every throw, including throws the code catches. After such a stop every stepping command was refused with "Cannot step after breaking on error", so the only option was to quit the session:

function caught_twice(xs)
    n = 0
    for x in xs
        v = try
            parse(Int, x)
        catch
            -1
        end
        n += v
    end
    return n
end
break_on(:throw); @enter caught_twice(["a", "1", "b"])
# c → stops at the throw for "a"; c / n → "Cannot step after breaking on error"

Now, when an interpreted frame catches the exception the session stopped for, a stepping command unwinds into that handler with JuliaInterpreter.unwind_exception:

• c continues from the handler (in the example: on to the throw for "b", then to the end),
• the other stepping commands stop at the start of the catch block.

Stepping after an uncaught error is still refused. The exception is kept in a new DebuggerState field, error_stopped_for. unwind_exception exists in all supported JuliaInterpreter versions.

Tests: continuing past caught throws (fails without the change), and the refusal after an uncaught error.
