Summary

This PR standardizes sourcelib parsing in openedx-events to keep metadata backward-compatible and consistent across event bus implementations.

What changed

• Added and used shared helper:

  from openedx_events.utils import parse_sourcelib_release

• Updated EventsMetadata sourcelib parsing to use packaging.version.Version(...).release.
• Ensured sourcelib remains a tuple of integers (release segment only).
• Added/updated tests to cover PEP 440 inputs (including post/dev/rc variants).

Behavior

• "11.2.0" → (11, 2, 0)
• "9.10.post1" → (9, 10)
• "1.2.3rc1" → (1, 2, 3)

Why

A recent Redis event bus change exposed inconsistencies around PEP 440 handling.
Keeping this logic in openedx-events avoids divergence across implementations and prevents breaking downstream consumers that expect sourcelib as tuple[int, ...].

Just a couple of little things, otherwise it looks good to me. Will you also be doing the follow-on PRs for the event bus repos?

[bmtcril]

Can you add a note here that only the release segment is kept and that additional information (pre/post/dev etc) is dropped?

[bmtcril]

We should add packaging as a direct dependency in requirements/base.in . It works right now, but only because it's being indirectly installed via celery / kombu.
