[jguz-pubnub]

Summary

• Rewrite README.md using the standard PubNub SDK README template (CLEN-3789 / CLEN-3802).
• Rewrite DEVELOPER.md: current Python versions (3.9–3.13), setup, tests, linting, call styles, daemon mode.

Deviations from CLEN-3802

• Quickstart example differs from the story's snippet: it publishes from the main thread after the connected event, uses no global, and a try/finally always unsubscribes, removes the listener and calls pubnub.stop().
• License name and contribution text use the story's values; the LICENSE file title is "PubNub Software Development Kit License Agreement".

Testing

• Ran the README Quickstart against a real keyset on Python 3.13; it printed Hello world and exited 0.
• Not yet verified: Python 3.9, failure paths, and that all documentation links resolve.
