fix: bump python version to 3.14

[mouadostor]

Changes

• bump python version to 3.14
• fix failing test

Issue

1. test was using requests_mock to pretend the queues were empty. However, requests_mock only patches the memory of the parent test process. Because Python 3.14 on Linux uses spawn by default for multiprocessing (which creates a completely fresh Python interpreter), the child process did not inherit the mock.
2. it attempted a real HTTP request to http://localhost:15672/api/queues/%2F
3. While the child process was sleeping for 2 seconds, parent test process hit its 1-second timeout limit
4. The TimeoutError caused agent to emit a "timeout" message before the "done" message. This resulted in the agent emitting 4 messages in total, instead of the 2 messages your test expected.

Fix

make the tests robust, predictable, and isolated from OS process quirks, we changed the testing strategy entirely:
Instead of trying to mock HTTP requests across process boundaries, we mocked multiprocessing.Process directly.
