JSONResultsReader iterator called on oneshot search does not iterate with for loop.

Start by reproducing the provided JSONResultsReader snippet with both oneshot and normal searches, then inspect the JSONResultsReader iterator entry point and any existing tests. Done means a reader from a oneshot search supports direct for-loop iteration without first converting it to a list, with coverage for the differing search modes.

Describe the bug
JSONResultsReader iterator called on oneshot search does not iterate with for loop.

To Reproduce
-run a oneshot search, the notice the for content/command[s] fails.

reader = JSONResultsReader(result_stream)
for item in reader:
    print(item)

Expected behavior
iterate through the results and take action on.

Splunk (please complete the following information):

• Version: Splunk Enterprise 9.1.1
• OS: Rocky Linux 9.6
• Deployment: Distributed/Clustered SH's and IDX's architecture

SDK (please complete the following information):

• Version: [2.1.0 and 2.1.1]
• Language Runtime Version: Python 3.12.3

Additional context
This issue is only impacting the "oneshot" type search, with "normal" type search successfully yields an iterable "reader" for reader = JSONResultsReader(result_stream).

The workaround is to do:

reader = JSONResultsReader(result_stream)
reader2 = list(reader)
for item in reader2:
    print(item)
